build: Fix "make install" failure on Android.
This patch fixes two problems with "make install" on Android:
1) On this platform, libtool is configured to relink libraries during
"make install".
This leads to a problem during the installation of libgettextsrc: The relink
command that libtool emits has the form
The option -lgettextlib resolves to $(libdir)/libgettextlib.a, not to
$(libdir)/libgettextlib-@VERSION@.so.
Thus the linker attempts to include many object files from libgettextlib.a
into libgettextsrc-@VERSION@.soT, but some of these reference global variables
in a non-PIC way, and the linker thus complains
ld.lld: error: relocation R_ARM_REL32 cannot be used against symbol 'program_name'; recompile with -fPIC
2) The installed executables don't have a RUNPATH property that points to the
directory that contains the shared libraries. Thus these executables don't run.
