Fix `checking if gcc static flag -static works' test.

On my linux build tree, I receive yes answer in in every package I
build except freetype for this test checking if gcc static flag
`-static' works

On freetype, no is received, unless bzip2 and zlib are disabled using

  ./configure --without-bzip2 --without-zlib

The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to
LDFLAGS and this broke static flag test.

* builds/unix/configure.raw: Update CFLAGS and LDFLAGS only after
LT_INIT has run.
