check for ld support of -Bsymbolic-functions; disable shared if not avail
this issue affects the last gpl2 version of binutils, which some people are still using out of aversion to gpl3. musl requires -Bsymbolic-functions because it's the only way to make a that's able to operate prior to dynamic linking but that still behaves correctly with respect to global vars that may be moved to the main program via copy relocations.
