Commit Message

Paolo Bonzini June 24, 2022, 8:27 a.m. UTC 
QEMU_CFLAGS is not available in pc-bios/s390-ccw/netboot.mak, but the Makefile
needs to access the flags passed to the configure script for the s390x
cross compiler.  Fix everything and rename QEMU_CFLAGS to EXTRA_CFLAGS for
consistency with tests/tcg.
