Richard Levitte 075f7e2c60 Remove automatic RPATH
Before OpenSSL 1.1.0, binaries were installed in a non-standard
location by default, and runpath directories were therefore added in
those binaries, to make sure the executables would be able to find the
shared libraries they were linked with.

With OpenSSL 1.1.0 and on, binaries are installed in standard
directories by default, and the addition of runpath directories is
therefore not needed any more.

#
# Helper makefile to link shared libraries in a portable way.
# This is much simpler than libtool, and hopefully not too error-prone.
#
# The following variables need to be set on the command line to build
# properly
# CC contains the current compiler. This one MUST be defined
CC=cc
CFLAGS=$(CFLAG)
# LDFLAGS contains flags to be used when temporary object files (when building
# shared libraries) are created, or when an application is linked.
# SHARED_LDFLAGS contains flags to be used when the shared library is created.
LDFLAGS=$(LDFLAG)
SHARED_LDFLAGS=$(SHARED_LDFLAG)
RC=windres
# SHARED_RCFLAGS are flags used with windres, i.e. when build for Cygwin
# or Mingw.
SHARED_RCFLAGS=$(SHARED_RCFLAG)
NM=nm
# LIBNAME contains just the name of the library, without prefix ("lib"
# on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so,
# .dll, ...). This one MUST have a value when using this makefile to
# build shared libraries.
# For example, to build libfoo.so, you need to do the following:
#LIBNAME=foo
LIBNAME=
# APPNAME contains just the name of the application, without suffix (""
# on Unix, ".exe" on Windows, ...). This one MUST have a value when using
# this makefile to build applications.
# For example, to build foo, you need to do the following:
#APPNAME=foo
APPNAME=
# DSTDIR is the directory where the built file should end up in.
DSTDIR=.
# SRCDIR is the top directory of the source tree.
SRCDIR=.
# OBJECTS contains all the object files to link together into the application.
# This must contain at least one object file.
#OBJECTS=foo.o
OBJECTS=
# LIBEXTRAS contains extra modules to link together with the library.
# For example, if a second library, say libbar.a needs to be linked into
# libfoo.so, you need to do the following:
#LIBEXTRAS=libbar.a
# Note that this MUST be used when using the link_dso targets, to hold the
# names of all object files that go into the target shared object.
LIBEXTRAS=
# LIBVERSION contains the current version of the library.
# For example, to build libfoo.so.1.2, you need to do the following:
#LIBVERSION=1.2
LIBVERSION=
# LIBCOMPATVERSIONS contains the compatibility versions (a list) of
# the library. They MUST be in decreasing order.
# For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2
# and libfoo.so.1, you need to do the following:
#LIBCOMPATVERSIONS=1.2 1
# Note that on systems that use sonames, the last number will appear as
# part of it.
# It's also possible, for systems that support it (Tru64, for example),
# to add extra compatibility info with more precision, by adding a second
# list of versions, separated from the first with a semicolon, like this:
#LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0
LIBCOMPATVERSIONS=
# LIBDEPS contains all the flags necessary to cover all necessary
# dependencies to other libraries.
LIBDEPS=

# For Darwin AKA Mac OS/X (dyld)
# Originally link_dso.darwin produced .so, because it was hard-coded
# in dso_dlfcn module. At later point dso_dlfcn switched to .dylib
# extension in order to allow for run-time linking with vendor-
# supplied shared libraries such as libz, so that link_dso.darwin had
# to be harmonized with it. This caused minor controversy, because
# it was believed that dlopen can't be used to dynamically load
# .dylib-s, only so called bundle modules (ones linked with -bundle
# flag). The belief seems to be originating from pre-10.4 release,
# where dlfcn functionality was emulated by dlcompat add-on. In
# 10.4 dlopen was rewritten as native part of dyld and is documented
# to be capable of loading both dynamic libraries and bundles. In
# order to provide compatibility with pre-10.4 dlopen, modules are
# linked with -bundle flag, which makes .dylib extension misleading.
# It works, because dlopen is [and always was] extension-agnostic.
# Alternative to this heuristic approach is to develop specific
# MacOS X dso module relying on whichever "native" dyld interface.
