[patch] [libobjc] fix build with --disable-shared and .la files

This addresses PR libobjc/78698, fixing the build with --disable-shared and .la
files available.  As mentioned in the bug report I'm not aware of a configure
check to write a check using LIBTOOL_LINK and LIBTOOL_COMPILE, because these
commands (using libtool) are only created by running the configure file,
therefore checking for the presence of a .la file.

Tested with a libgc installation in /opt/gcc/include, /opt/gcc/lib32,
/opt/gcc/lib64 and configured with

--prefix=/opt/gcc7 --enable-languages=c,c++,objc --disable-shared
--enable-objc-gc=yes --with-multilib-list=m32,m64 --enable-checking=release
--disable-bootstrap --with-target-bdw-gc-include=/opt/gcc/include

Ok for the trunk?
