When building an nvptx offloading configuration on openSUSE Leap 15.3, the
site script /usr/share/site/x86_64-unknown-linux-gnu is activated, setting
libexecdir to ${exec_prefix}/lib rather than ${exec_prefix}/libexec:
...
| # If user did not specify libexecdir, set the correct target:
| # Nor FHS nor openSUSE allow prefix/libexec. Let's default to prefix/lib.
|
| if test "$libexecdir" = '${exec_prefix}/libexec' ; then
| libexecdir='${exec_prefix}/lib'
| fi
...
However, in libgomp libgomp/plugin/configfrag.ac we hardcode libexec:
...
# Configure additional search paths.
if test x"$tgt_dir" != x; then
offload_additional_options="$offload_additional_options \
-B$tgt_dir/libexec/gcc/\$(target_alias)/\$(gcc_version) \
-B$tgt_dir/bin"
...
Fix this by using /$(libexecdir:\$(exec_prefix)/%=%)/ instead of /libexec/.
Tested on x86_64-linux with nvptx accelerator.
libgomp/ChangeLog:

* plugin/configfrag.ac: Use /$(libexecdir:\$(exec_prefix)/%=%)/
instead of /libexec/.
