* introducing dependencies on readelf and objdump. At least elsewhere
in the strip code, we use `file` to locate shared libraries. And you
can get the SONAME bit out of objdump -p, which would at least limit
this to one tool.
readelf and objdump are both in binutils, but I've noticed that objdump
doesn't support the file format generated by tcc although readelf does
and it's a valid ELF file afaict.
eu-objdump (elfutils) can't output that much, but it understands tcc's
format and outputs pretty nice architecture information. Sadly I have no
idea if that's portable.
Now I'm using readelf (binutils) and eu-objdump (elfutils). I think it's
fine since both are in core and you only need them for makepkg anyway.
We have pacman/makepkg users on Linux, OSX, BSD, Hurd, Cygwin...
Whatever is used here needs to be portable to all those. I do not
believe elfutils is particularly portable...
I'd use objdump (binutils), but I don't know if it's compatible with
binaries not generated by gcc (at least tcc doesn't work) and I can't
really assume all users use gcc either.
There is a "portability" patch [1] for elfutils. Not sure if that is
what we need though.
That portability patch seems to be mainly to add compatibility to older
Linux systems, not for non-Linux systems.
