[Pkg-electronics-devel] Bug#1003500: gcc-sh-elf: reproducible builds: embeds path to various binaries

The paths to various binaries are embedded which differs on a usrmerge
vs. non-usrmerge system.

Patch attached which passes variables to configure to use the
non-usrmerge locations, as usrmerge installations typically have
compatibility symlinks, but not vice-versa. The patch also sets
variables to ensure consistent values for bash, which can be triggered
when /bin/sh points to bash.

This patch alone does not fix all reproducibility issues (e.g. build
paths, which are only tested on unstable and experimental), but should
significantly improve the reproducibility, especially in
bookworm/testing.


Thanks for maintaining gcc-sh-elf!


live well,
