Log Message:
Fix regression introduced to GCC10, by which inline assembler codes for
403/405 are miscompiled.

Redundant .machine directive introduced by upstream commit
2d94f7dea9c73ef3c116a0ddc722724578a860fe:

        https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=2d94f7dea9c73ef3c116a0ddc722724578a860fe

clobbers CPU flags passed to assembler. This results in miscompile for
inline assembler codes specific to 403/405 processors, at least.

Therefore, revert this commit locally.

The problem has been reported as 100107 to upstream:

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100107

OK mrg
