Fix 'duplicate symbol' error for tests using multiple static libs (OS X)
Issue #263 (bdwgc).
If configured with --enable-static, libtool passes libgc.a to gcc
twice (with a relative path and with an absolute one) when linking
tests that depend on libcord.a, libgccpp.a or libstaticrootslib_test.a
which, in turn, depends on libgc.a. Double specification of libgc.a
seems to confuse ld tool of MacOS 10.14.
The workaround is to omit libgc.la in *_LDADD specification of the
mentioned tests when the shared libraries are not requested, at least.
* configure.ac (ENABLE_SHARED): New AM_CONDITIONAL.
* cord/cord.am (cordtest_LDADD): Do not add libgc.la unless
ENABLE_SHARED; add comment.
* tests/tests.am (staticrootstest_LDADD): Likewise.
* tests/tests.am [CPLUSPLUS && !AVOID_CPP_LIB] (test_cpp_LDADD):
Likewise.
