Thanks for review! I am going to use
AM_CONDITIONAL(HAVE_ZSTD, test "$pkg_cv_ZSTD_LIBS" != "")
if HAVE_ZSTD
check_SCRIPTS += gdb_index_test_2_zstd.sh
check_DATA += gdb_index_test_2_zstd.stdout
MOSTLYCLEANFILES += gdb_index_test_2_zstd.stdout gdb_index_test_2_zstd
gdb_index_test_cdebug_zstd.o: gdb_index_test.cc
$(CXXCOMPILE) -O0 -g -Wa,--compress-debug-sections=zstd -c -o $@ $<
gdb_index_test_2_zstd: gdb_index_test_cdebug_zstd.o gcctestdir/ld
$(CXXLINK) -Wl,--gdb-index $<
gdb_index_test_2_zstd.stdout: gdb_index_test_2_zstd
$(TEST_READELF) --debug-dump=gdb_index $< > $@
endif
autoconf generated gold/configure uses test "$pkg_cv_ZSTD_LIBS" != ""
to define HAVE_ZSTD_TRUE= and HAVE_ZSTD_FALSE='#'
