Merge branch 'icc-include-fix' into 'main'

>>> import archspec.cpu
>>> host = archspec.cpu.detect.host()
>>> host.family.compilers['gcc'][0]['name']
'x86-64'
---
>>> host.family.compilers['gcc'][0]['name']
'powerpc64le'

Note mostly to myself: `-idirafter` does not work on ppc, the directory is called `/usr/include/powerpc64le-linux-gnu/`, but `platform.machine()` returns `ppc64le`. No need for an immediate fix, as we will move most of this to spack-environments. Archspec would know the correct information: ``` >>> import archspec.cpu >>> host = archspec.cpu.detect.host() >>> host.family.compilers['gcc'][0]['name'] 'x86-64' --- >>> host.family.compilers['gcc'][0]['name'] 'powerpc64le' ``` Maybe there is an easier path to that information?
