configure: do not duplicate CPU_CFLAGS into QEMU_LDFLAGS

Browse Source 
Since commit 4dba278908 ("configure, meson: move CPU_CFLAGS out of
QEMU_CFLAGS"), CPU_CFLAGS is included in the link commands both during
configure and (via config-meson.cross) during meson.  It need not be
added separately to QEMU_LDFLAGS.
