Hi,
I just send a patch to the mailing list, that correctly fixes this issue.
The real issue is that before 020d5f0, a baremetal gcc-cross was built
without proper sysroot paths and the libgcc (and maybe also other
builds) used headers from the host.
I guess this could lead to more built errors in other recipes, that rely
on the availability of libc headers, but theses recipes must be fixed then.
IMHO the bug I fixed with 020d5f0 has far greater reach than I expected,
because it has the potential to poison a lot of builds with host headers
and could have hid a lot of problems in the past.
PLEASE do not merge the revert, but merge the fix to libgcc instead.
Jörg

While this change has good intentions, unfortunaly, it completely
breaks baremetal setup (at least for ARM arch).
The line this change removes seems to mask an underlying issue,
but until that issue is fully understood and resolved, let's
revert it and restore the working baremetal behavior.
For more details please see the following discussion:
