Mac M1 support

[coderamen666]

The toolchain does not compile on mac m1 due to a missing -lintl. what can i do?

Looks like mac removed icu4c in some recent versions of osx.

brew install wget icu4c texinfo gmp mpfr libmpc binutils
CFLAGS=-I/opt/homebrew/include LDFLAGS=-L/opt/homebrew/lib ./build-posix64-toolchain.sh

Now I'm seeing some GCC errors:

error: functions that differ only in their return type cannot be overloaded
extern const char *strsignal (int);
../../gcc-source/gcc/system.h:540:20: error: functions that differ only in their return type cannot be overloaded

Let me investigate a bit more...
