There is also transform_pass_with_warning...
But that seems to only put a warning into .work.log

But this is exactly the reason I ask, in other words, I cannot seem to 
find anything but specifically '-specs=' as the correct syntax, in 
particular as found in the "Using the GNU Compiler Collection"

Doesn't seem to me that pkgsrc should inverse the portability exigence 
if not totally warranted.

Do you happen to have a reference of something with '-specs filename' 
other than these aforementioned pkgsrc buildlink3.mk files?

If so, then I'll make a bug report upstream to ccache.samba.org.

As for pkgsrc, couldn't seem to find a way safely pop the next arg in 
transform-gcc, but the following seems to do the trick:
