Tom de Vries 78e4948694 [gdb/build] Fix gdbserver build with -fsanitize=address 
When doing a gdbserver build with CFLAGS/CXXFLAGS/LDFLAGS=-fsanitize=address
we run into:
...
ld: ../libiberty/libiberty.a(safe-ctype.o):
relocation R_X86_64_32 against `.data' can not be used when making a
shared object; recompile with -fPIC
collect2: error: ld returned 1 exit status
make[1]: *** [libinproctrace.so] Error 1
...

This started with commit 9664849417 "gdbsupport: make use of safe-ctype
functions from libiberty", which introduced a dependency of libinproctrace.so
on libiberty.

Fix this in gdbserver/Makefile.in by using a setup similar to what is done in
gcc-repo/src/libcc1/Makefile.am, such that ../libiberty/noasan/libiberty.a is
used instead.

Build on x86_64-linux, both with and without -fsanitize=address.

gdbserver/ChangeLog:

2021-01-07  Tom de Vries  <tdevries@suse.de>

	* Makefile.in (LIBIBERTY_NORMAL, LIBIBERTY_NOASAN, LIBIBERTY_PIC):
	(LIBIBERTY_FOR_SHLIB): New var.
	(LIBIBERTY): Set using $(LIBIBERTY_NORMAL).
	(IPA_LIB): Use LIBIBERTY_FOR_SHLIB instead of LIBIBERTY in target rule.
