Drop APG_CFLAGS (which is empty) to correctly set CFLAGS with
TARGET_CFLAGS (which will contain -static) passed by
TARGET_CONFIGURE_OPTS. Moreover, pass TARGET_CFLAGS to FLAGS which is
used to build apgbfm. This will fix the following musl static build
failure raised since the addition of the package in commit
99eb1a7019:
