Improve the build rule for apinames.

Browse Source 
* builds/unix/configure.raw: copy `CFLAGS` &
`LDFLAGS` values to `CFLAGS_BUILD` &
`LDFLAGS_BUILD`, in a self-hosting case.

* builds/unix/unix-cc.in: set `CCexe_CFLAGS` &
`CCexe_LDFLAGS` by `CFLAGS_BUILD` &
`LDFLAGS_BUILD`.

In some confused environments, simple building
like `cc -o apinames apinames.c` is no longer
able to build an executable running on the host.

The validity of `CC` is tested with consideration
of `CFLAGS` and `LDFLAGS`, thus, duplicating
`CFLAGS` & `LDFLAGS` to `CCexe_CFLAGS` &
`CCexe_LDFLAGS` (via XXX_BUILD) would be slightly
safer in a self-hosting build.

Fixes the issue #1296.
