Title:
  configure script --extra-cflags not passed to config-meson.cross

Status in QEMU:
  Expired

Bug description:
  Since qemu 5.2, when building, the configure would not finish, but
  would return this error instead:

     qemu ../meson.build:852:2: ERROR: C header 'sasl/sasl.h' not found

  This is for a cross build, and I invoke qemu with the --extra-cflags
  and --extra-ldflags containing all the proper paths to the headers,
  libraries etc. It worked properly with qemu 3.1 to 5.1.

  After looking into the configure script, it seems that meson is passed
  the CFLAGS environment variable instead of QEMU_CFLAGS, and only the
  latter contains the --extra-cflags argument:

      echo "c_args = [${CFLAGS:+$(meson_quote $CFLAGS)}]" >> $cross

  Using the CFLAGS and LDFLAGS environment variable instead of --extra-
  cflags and --extra-ldflags fixes the issue.
