[PATCH] Revert "tclibc-baremetal.inc: fix gcc-cross EXTRA_OECONF"

[Denys Dmytriyenko]

From: Denys Dmytriyenko <denys@konsulko.com>

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:
https://lists.openembedded.org/g/openembedded-core/topic/121486589

This reverts commit 020d5f018616bc48eae3a23d5498dec3c78a1386.

Re: [OE-core] [PATCH] Revert "tclibc-baremetal.inc: fix gcc-cross EXTRA_OECONF"

[Jörg Vehlow]

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

Hi Denys,

I wonder if the fix is that this should be:

    EXTRA_OECONF:append:pn-gcc-cross-${TARGET_ARCH}

Best regards,

That would fix the bad behavior but would result in the same build issue 
that we see when just removing it.  I think the issue might be fixed by 
the gcc fix that Jeorg sent to the list.  I'm going to test this build 
with his patch right now and see if it fixes everything.

Yeah, I noticed the order of overrides is backwards, but don't think it 
matters and the issue is deeper it seems. I see that Joerg send a follow up 
patch to address it, but I haven't been able to test it yet.
