When this is done PostgreSQL fails to build, with error ==== STRIPPROG='strip -x' /bin/sh ../../../config/install-sh -c -m 644 -s libpq.a '/wrkdirs/usr/ports/databases/postgresql13-client/work/stage/usr/local/lib/libpq.a' strip: error: '/wrkdirs/usr/ports/databases/postgresql13-client/work/stage/usr/local/lib/_inst.20299_': not stripping symbol '.L.str' because it is named in a relocation ==== This occurs because llvm-objcopy is more strict, compared to GNU strip or ELF Tool Chain strip. When -x is specified (i.e., discard all non-global symbols) but the object to strip contains symbols that cannot be discarded LLVM's strip emits an error. GNU and ELF Tool Chain strip instead just retain the referenced non-global symbols. Within the FreeBSD ports collection TCL and PostgreSQL are the only significant software packages affected by this issue. TCL addressed this by using --strip-unneeded instead of -x.
