If I do:
...
$ cat conftest.c
int
main ()
{
return 0;
}
...
and copy the corresponding command from libatomic/config.log, and add -v
-Wl,-v, I get:
...

Looking into collect-ld, it has:
...
ORIGINAL_LD_FOR_TARGET="/home/vries/oacc/trunk/install/offload-nvptx-none/nvptx-none/bin/ld"
...
which is a link to nvptx-none-ld:
...
$ /home/vries/oacc/trunk/install/offload-nvptx-none/nvptx-none/bin/ld --help
Usage: nvptx-none-ld [option...] [files]
Options:
-o FILE Write output to FILE
-v Be verbose
-l LIBRARY Link with LIBRARY
-L DIR Search for libraries in DIR
--help Print this help and exit
--version Print version number and exit

...
Can you do the same: create conftest.c, copy command from config.log, add
-Wl,-v -v. Then do you see collect-ld being called? If so, does collect-ld have
the correct linker hardcoded in there?
