RE: [Linaro-TCWG-CI] gcc-15-4672-gdf4af89bc3e: Failure on arm

[Sam James via Gcc-regression]

It's not possible to do a profiledbootstrap via cross. It might be
possible for the Linaro CI to extract the bad preprocessed source and
share the options used to build it (options at least should be in the
log) but that won't help if the compiler is miscompiled...
