New: arceb-buildroot-linux-uclibc ld uses incorrect default format

Bug ID: 9016
Summary: arceb-buildroot-linux-uclibc ld uses incorrect default
format
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: uwe at hermann-uwe.de
CC: buildroot at uclibc.org
Target Milestone: ---

With the arceb-buildroot-linux-uclibc toolchain you can get issues like this when compiling certain files/libs:

~/buildroot-arceb-buildroot-linux-uclibc/output/host/usr/arceb-buildroot-linux-uclibc/bin/ld:
ERROR: Endian Match failed. Attempting to link blah.a(foo.o) with binary baz.o of opposite endian-ness

The reason seems to be that "ld" uses the incorrect default output format. Adding "-BE" would probably fix it, but IMHO it's a bug already that the default is not set to BE (but please correct me if I'm wrong).

ARC, little endian, correct default:
~/buildroot-arc-buildroot-linux-uclibc/output/host/usr/arc-buildroot-linux-uclibc/bin/ld --print-output-format
elf32-littlearc

ARC, big endian, WRONG default (should be "elf32-bigarc"):
~/buildroot-arceb-buildroot-linux-uclibc/output/host/usr/arceb-buildroot-linux-uclibc/bin/ld --print-output-format
elf32-littlearc

For comparison, here's another LE/BE toolchain example where this is handled correctly:

AARCH64, little endian, correct default:
~/buildroot-aarch64-buildroot-linux-gnu/output/host/usr/aarch64-buildroot-linux-gnu/bin/ld --print-output-format
elf64-littleaarch64

AARCH64, big endian, correct default:
~/buildroot-aarch64_be-buildroot-linux-gnu/output/host/usr/aarch64_be-buildroot-linux-gnu/bin/ld --print-output-format
elf64-bigaarch64

--- Comment #1 from Vlad Zakharov <[email protected]> --- Hi,

I built toolchain in buildroot, tried to run your examples and got the following results:
--------------------->8------------------- .../arceb-buildroot-linux-uclibc/bin/ld --print-output-format elf32-bigarc
--------------------->8-------------------

Please provide more about conditions under which the failure occurred, e.g. what toochain version and git revision were used.
That would help us to catch and fix the issue.

Thanks,
Vlad.
