[ft-devel] builds/unix/configure.raw is updated.

Hi,

During the work for Win64 with cross build, I found
2 issues of existing builds/unix/configure.raw.

1) After the check of suffix for native executable
by CC_BUILD, the temporal files are not removed.
"a.out" is left in the working directory.

2) GCC for cross build is not recognized as gcc,
so "-Wall" "-pedantic -ansi" are not passed to
cross compiler. As a result, default warning
level is more relaxed than native build.

Both issues are fixed in git HEAD.
