configure.ac: make cross-compiler detection stricter
Be more precise at detecting cross-compilation case.
Before the change configuration
$ ./configure --host=x86_64-pc-linux-gnu --target=x86_64-gentoo-linux-musl
was not considered a cross-target. Even though libcs are different (`glibc` vs. `musl`).
Without this patch build fails as:
```
"inplace/bin/ghc-cabal" check libraries/integer-gmp
"inplace/bin/ghc-cabal" configure libraries/integer-gmp dist-install \
--with-ghc="/home/slyfox/dev/git/ghc/inplace/bin/ghc-stage1" \
--with-ghc-pkg="/home/slyfox/dev/git/ghc/inplace/bin/ghc-pkg" \
--disable-library-for-ghci --enable-library-vanilla --enable-library-for-ghci \

--with-alex="/usr/bin/alex" --with-happy="/usr/bin/happy"

If you meant to cross compile, use `--host'.

make[1]: *** [libraries/integer-gmp/ghc.mk:5: libraries/integer-gmp/dist-install/package-data.mk] Error 1
make: *** [Makefile:126: all] Error 2
```
Note: here `ghc-stage1` is assumed to target `musl` target but is passed
`glibc` toolchain. It happens because initial ./configure phase did not
detect host/target as different.
