Bug#1038908: binutils-msp430: reproducible builds: embeds build path in various binaries

[Vagrant Cascadian]

Source: binutils-msp430
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The build path is embedded in various binaries:

  https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/binutils-msp430.html

  /usr/bin/msp430-addr2line

  /build/1st/binutils-msp430-2.24~ti1/binutils-2.40/bfd/elflink.c:9935
  vs.
  /build/2/binutils-msp430-2.24~ti1/2nd/binutils-2.40/bfd/elflink.c:9935

The attached patch to debian/rules fixes this by using the default
clfags for dpkg-buildflags, which includes -ffile-prefix-map to avoid
embedded build paths.

An alternate approach which may fix this issue is to switch to using a
newer debhelper compat level and dh, which may bring numerous other
benefits as well.

According to my local tests, with this patch applied binutils-msp430
should build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining binutils-msp430!

live well,
  vagrant
