Support FreeBSD.

Based on patch from Arrigo Marchiori.
#11

Use gmake instead of make (that is: GNU Make instead of BSD Make).
Use the standard Clang compiler instead of the standard GCC.
Remove the --verbose option from the patch invocations inside
unpack-gcc.sh (BSD Patch does not support that option).

Also, change script shebang for FreeBSD :
/bin/bash -> /usr/bin/env bash
