Bug#1065598: gcc-13-offload-nvptx: openmp offload compile fails due to missing libgomp.spec

[Giacomo Mulas <giacomo.mulas@inaf.it>]

Package: gcc-13-offload-nvptx
Version: 13.2.0-18
Severity: grave
Justification: renders package unusable

Dear Maintainer,

due to a different organisation in file installation with respect to gcc-12-offload-nvptx, compiling code to offload openmp to nvptx fails with the following:
x86_64-linux-gnu-accel-nvptx-none-gcc-13: fatal error: cannot read spec file 'libgomp.spec': No such file or directory
compilation terminated.
nvptx mkoffload: fatal error: x86_64-linux-gnu-accel-nvptx-none-gcc-13 returned 1 exit status
compilation terminated.
lto-wrapper: fatal error: /usr/libexec/gcc/x86_64-linux-gnu/13//accel/nvptx-none/mkoffload returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed

While gcc-12-offload-nvptx installed executables, includes, and libs under /usr/lib/gcc/x86_64-linux-gnu/12/accel/nvptx-none, and found them, gcc-13-offload-nvptx does not appear to install them anywhere, nor to depend on any other separate package that does. This effectively renders the package unusable. While the gcc-12 offload still works, gcc-13 is now the default compiler on sid, meaning that trying to compile openmp to offload to nvptx with the default compiler fails.

Thanks in advance, best regards
Giacomo Mulas
