src/lib/libc/string: Makefile.inc
Log Message:
for GCC, built memset.c with -fno-builtin. this avoids GCC 10 compiling
memset() and emitting calls to memset() where it seems code that looks
like what memset() does, which ends up recursing and blowing the stack.
this makes mips userland with GCC 10 work.
