CMake commit faa950a155 ("try_compile: Run native build tool with verbose output")
did not play well with these versions of openmp, which have a faulty
failure regex that considers "unknown" in the build output to indicate
a failure. When cross compiling, the string "unknown" is very likely
to occur as part of triples. Fix by backporting a patch that improves
the failure regex check to not be tripped up by triples.
The same problem affects LLVM 11 and possibly earlier, but the patch
doesn't apply that far back, so I didn't bother for now.
Fixes: b8ac5b6cfb ("cmake: 3.25.3 -> 3.26.4")

The OpenMP subproject of LLVM contains the components required to build an
|
|
executable OpenMP program that are outside the compiler itself.
|
|
Contains the code for the runtime library against which code compiled by
|
|
"clang -fopenmp" must be linked before it can run and the library that
|
|
supports offload to target devices.
