+With that, we may then run plain 'autoreconf' for all of GCC's subpackages,

+the applicable combination of 'aclocal', 'autoconf', 'autoheader'.
+
+See also 'AC_CONFIG_MACRO_DIRS'/'AC_CONFIG_MACRO_DIR' usage elsewhere.

+Pre-5.0 GCC does not have a cpuid.h header installed on the system, so

+https://stackoverflow.com/questions/22160093/inconsistent-operand-constraints-in-an-asm
+Pre-5.0 GCC does not support PIC inline ASM that touches ebx (as
