This broke llvm-gcc bootstrap on linux x86-64. The build halts on

echo | /usr/local/espindola/llvm/llvm-gcc-build/./gcc/xgcc
-B/usr/local/espindola/llvm/llvm-gcc-build/./gcc/
-B/usr/local/x86_64-unknown-linux-gnu/bin/
-B/usr/local/x86_64-unknown-linux-gnu/lib/ -isystem
/usr/local/x86_64-unknown-linux-gnu/include -isystem
/usr/local/x86_64-unknown-linux-gnu/sys-include -E -dM - | \
	  sed -n -e 's/^#define \([^_][a-zA-Z0-9_]*\).*/\1/p' \
		 -e 's/^#define \(_[^_A-Z][a-zA-Z0-9_]*\).*/\1/p' | \
	  sort -u > tmp-macro_list

With cc1 using 100% cpu.
