--- Comment #9 from David Edelsohn <dje at gcc dot gnu.org> ---
GCC is working correctly.  The file prologue generated by GCC for a C file now
includes

.machine power8

The example is a pre-processed assembly file.  Note the file actively pushes
and pops the machine type.

The assembly file incorrectly assumes that GCC will invoke the assembler with a
command-line option enabling a default ISA level sufficient for the
instructions in the file.  This is a bad assumption.  Even if we create a
kludge in GCC to invoke the assembler an arbitrary ISA level, this is bad
assumption.  The GLIBC file is buggy.
