Bug#914128: perl: usrmerge issues

[Niko Tyni]

Source: perl
Version: 5.28.0-3
User: md at linux.it
Usertags: usrmerge

Diffoscoping a perl built on a usrmerged [1] system with
one built on a non-usrmerged system reveals the configure
process hardcoding some paths in the build results,

[1] https://wiki.debian.org/UsrMerge

Snippets from config.h, Config.pm, Config_heavy.pl, config.sh.debug.gz
and so forth include things below.

The /bin vs. /usr/bin command paths can probably be fixed/worked around
by passing the full /bin paths (which should work on both systems)
directly to Configure. The /lib64 thing in libpth / glibpth looks like
a bug to me. I don't know what to do about libsdirs and libsfound.

There's potential breakage if perl is built on a usrmerged system but
run on a non-usrmerged one. I suspect the breakage would not be very bad
and that most of this is cosmetic and not widely used.

Filing this to at least document the issue for now.
