Bug ID: 32314
   Summary: Profile script in elfutils-debuginfod-client throws
error on login
   Product: elfutils
   Version: unspecified
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: debuginfod
  Assignee: unassigned at sourceware dot org
  Reporter: ngren...@cygnusx-1.org
CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

With elfutils 0.192 on Fedora 41 with a shell set to zsh I get the error below.
This can be argued to be a packaging bug of Fedora's, and I did file a bug
report with them, linked below. Yet I see multiple things that could be better
at this upstream level.

1. Both of these configure options are required to make
/etc/profile.d/debuginfod.sh behave with zsh. This could be simplified into one
configuration option, or something like it.

--enable-debuginfod-urls=%{dist_debuginfod_url} \
--enable-debuginfod-ima-cert-path=%{_sysconfdir}/debuginfod \

2. The /etc/profile.d/debuginfod.sh script could either be made to work with no
certpath file when the shell is zsh, the template could be modified such that
if the second configure option is not specified it the if statement for
*.certpath is not included, or both.

3. Is --enable-debuginfod-ima-cert-path meant to be something like
/etc/ssl/certs?

Error message:
/etc/profile.d/debuginfod.sh:14: no matches found: /etc/debuginfod/*.certpath

full log when building elfutils in openwrt

elfutils: 0.191
When compiling elfutils in OpenWRT, gcc warn potential null pointer dereference
with lto enabled. If I disable it or use `-Wno-null-dereference` then the build
would pass with no problems.
