powerpc: Ensure the else case of feature sections will fit ...
When we create an alternative feature section, the else case must be the
same size or smaller than the body. This is because when we patch the
else case in we just overwrite the body, so there must be room.
Up to now we just did this by inspection, but it's quite easy to enforce
it in the assembler, so we should.
The only change is to add the ifgt block, but that effects the alignment
of the tabs and so the whole macro is modified.
Also add a test, but #if 0 it because we don't want to break the build.
Anyone who's modifying the feature macros should enable the test.
