I think there is too much MKGCC conditional logic

Firstly, doesn't set EXTERNAL_GCC_SUBDIR if MKGCC=no .. the
.endif could move up a paragraph I think.

Then inside the libgcc directory there is some logic. I think the libgcc
directory should not be descended into if it is not required, rather than
descending into it and deciding we want out.
