Actually its Dan Kegel's patch (my mistake).  Its supposed to ensure that
the right version of as is used.

I've tried several.  There seems to be only one failure with make check
(and 13 tests not run)

ld-discard/extern

I've no idea what failure of this test means but its pretty consistent
through the different versions I've tried.  I'm hoping it is something
that should be in the site.exp file (used to disable tests that aren't
valid for a particular platform?).

I thought this meant specifically glibc headers.  Otherwise how do you
explain the combination of --without-headers & --with-newlib?
