configure: fix parameter expansion of --cross-cc-cflags options

Without this fix, any use of --cross-cc-cflags-* causes a message like:
$ ../configure --cross-cc-ppc64le=clang --cross-cc-cflags-ppc64le="-target powerpc64le-unknown-linux-gnu -sysroot ..."
../configure: 1: eval: cross_cc_cflags_--cross-cc-cflags-ppc64le=-target: not found
../configure: 3816: export: cross_cc_cflags_--cross-cc-cflags-ppc64le: bad variable name
