This still isn't perfect. When the common/xbps-src/shutils/chroot.sh
function chroot_init() is called, the value for $XBPS_FFLAGS, which is
defined in common/build-profiles/bootstrap.sh, is empty.
Put the immediate value into the generated /etc/xbps/xbps-src.conf
file until someone finds out where passing the value of $XBPS_FFLAGS
throughout the scripts is missing.
