Thomas Petazzoni 9bccca26fb procps-ng: fix BR2_STATIC_LIBS=y build
The procps-ng package currently fails to build on BR2_STATIC_LIBS=y
configurations. Indeed, by default NUMA support is enabled, and it
requires dlopen(). As hinted by the configure script, passing
--disable-numa allows to disable NUMA support.

However, once this is done, another issue pops up: dlopen() is also used
by the SELinux support. But even when SELinux support is disabled, the
procps-ng code incorrectly includes <dlfcn.h>. This is addressed by the
addition of a patch.

Fixes:

Subject: [PATCH] ps/output.c: include <dlfcn.h> only when necessary
dlopen() functionality is only used when SELinux support is enabled, so
<dlfcn.h> only needs to be included when ENABLE_LIBSELINUX is
defined. This fixes the build in configurations where <dlfcn.h> is not
available.
