Robert Maynard 764606e256 CMakeDetermineCompilerABI: Extract lib arch from implicit object file paths 
The NVHPC compiler does not have any implicit link directories that can
be used to detect `CMAKE_LIBRARY_ARCHITECTURE`, but it does have
implicit object files.  Extract implicit object file paths from link
lines and check them for the `CMAKE_LIBRARY_ARCHITECTURE` pattern.

Issue: #22024

Robert Maynard 5d44d73bbe CMakeDetermineCompilerABI: Revert "Parse library arch from versioned paths" 
The change in commit 657fc3a9a7 (CMakeDetermineCompilerABI: Parse
library arch from versioned paths, 2021-02-03, v3.20.0-rc1~40^2) caused
`CMAKE_LIBRARY_ARCHITECTURE` to be populated on non-multiarch platforms
if their compilers happen to use `$arch/$version` library directories.
Revert the use of versioned library paths.

Robert Maynard 657fc3a9a7 CMakeDetermineCompilerABI: Parse library arch from versioned paths 
Teach CMake how to extract `CMAKE_<LANG>_LIBRARY_ARCHITECTURE` from
versioned paths such as `/usr/lib/gcc/x86_64-linux-gnu/9`. These kind of
paths are generated by NVHPC compilers.
