Comment (by Cebtenzzre):

 -fPIC is in the flags now, but the linker still fails:
 {{{
 /opt/local/libexec/gcc10-bootstrap/bin/gcc -pipe -fPIC -DNDEBUG
 -DCHECK_FUNCTION_EXISTS=pthread_create -arch i386 -mmacosx-version-
 min=10.4 -Wl,-search_paths_first -Wl,-headerpad_max_install_names -static-
 libstdc++ -static-libgcc

 /usr/bin/ld: CMakeFiles/cmTC_999e1.dir/CheckFunctionExists.c.o has
 external relocation entries in non-writable section (__TEXT,__text) for
 symbols:
 _pthread_create

 }}}

 And this is a build error I didn't notice before because I had my PATH set
 wrong:
 {{{
