[PATCH] build-many-glibcs.py: Fix “glibcs i686-gnu --strip”

[Florian Weimer]

As posted, this change depends on the build-many-glibc.py for built-in
system call tables, but this addresses a pre-existing issue.

Verified that stripping works on x86_64-linux-gnu, i686-linux-gnu,
x86_64-linux-gnu powerpc64le-linux-gnu (the installed files are actually
unchanged there), and that i686-gnu now has stripped shared objects.

Thanks,
Florian

Hurd sues an empty prefix, so the linker scripts end up in /lib, the
find command picked them up, and stripping them failed because they
are not ELF files.

This is OK (with s/sues/uses/ in the log message).
