Remove old workaround (strip-debug) for translator-pexes, add line info.
Remove old workaround (strip-debug) for translator-pexes, add line info.

I can no longer reproduce the file size difference in
(a) stripping debug info from the pexe, then stripping again
at the nexe level

vs

(b) not stripping from pexe, only stripping nexe

The old difference came in the eh_frame sections. It looks like
now the eh_frame sections are always as big as the
not-stripped case so the workaround isn't doing anything.

Since we're not seeing the difference anymore, remove the
workdaround so that it's not so confusing where the stripping
happens (only 1 place now). Also go ahead and compile the pexes
with -gline-tables-only, so that there's at least some debug
info if you want to debug the pexes or symbolize them e.g.
for profiling.
