On Android, within the termux environment, I encountered two problems during the "make install" phase of GNU gettext. The attached patch fixes them.

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
  $CC -shared -fPIC -DPIC .libs/*.o -L$(libdir) ... -lgettextlib ... -o .libs/libgettextsrc-@VERSION@.soT
The option -lgettextlib resolves to $(libdir)/libgettextlib.a, not to $(libdir)/ 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.
