           Summary: Setting MACHINE in environment is fatal when building
                    binutils-cross
           Product: Openembedded
           Version: Angstrom
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Build
        AssignedTo: openembedded-issues at lists.openembedded.org
        ReportedBy: pmiscml at gmail.com
         QAContact: tinderbox-oe at gmx.net


Having got a habit of multi-machine builds, I usually run bitbake like:

"MACHINE=<mach> bitbake ..."

Now I decided to make full rebuild, had MACHINE=h4000 and got following while
building glibc-intermediate:

| checking for .symver assembler directive... yes
| checking for ld --version-script... no
| *** WARNING: You should not compile GNU libc without versioning. Not using
| *** versioning will introduce incompatibilities so that old binaries
| *** will not run anymore.
| *** For versioning you need recent binutils (binutils-2.8.1.0.23 or newer).
| checking for .previous assembler directive... yes
| checking for .protected and .hidden assembler directive... yes
| checking whether __attribute__((visibility())) is supported... yes
| checking for broken __attribute__((visibility()))... no
| checking for broken __attribute__((alias()))... no
| checking whether to put _rtld_local into .sdata section... no
| checking for arm-angstrom-linux-gnueabi-readelf...
arm-angstrom-linux-gnueabi-readelf
| checking for .preinit_array/.init_array/.fini_array support... no
| configure: error: Need linker with .init_array/.fini_array support.
| FATAL: oe_runconf failed

After some checking, I figured that binutils-cross were configured with ARCH
like "arm:h4000". I attach diff of
binutils-cross-2.17.50.0.5-r1/binutils-2.17.50.0.5/build.i686-linux.arm-angstrom-linux-gnueabi/ld/earmelf_linux_eabi.c
- broken vs normal version.


So, there need to be some precaution when building such stuff with MACHINE
passed via environment.
