Fix build during cross-compilation as it fails to detect that our prefixed
compiler is gcc, and falls back to executing code to determine type sizes:
| configure: using code run method to find basic types
| checking for equivalent simple type of size_t...
| configure: error: in `/data/poky-master/tmp/work/core2-32-poky-linux/socat/1.7.2.4-r0/build':
| configure: error: cannot run test program while cross compiling
This is caused by configure.in assuming that $CC can be literally compared with
"gcc" to determine if the compiler is GCC. Our gcc is host-prefixed so this
test fails, however autoconf provides $GCC for this purpose (which was used up
to 1.7.2.3).
