[v2 0/4] grub & eglibc fixes for fedora 17 alpha

[nitin.a.kamble]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

These are various grub fixes for correctly building grub recipes for various targets.
These are tested for emenlow, sugerbay, qemux86, qemux86-64 machines

The eglibc commits is thes same as in the v1 pull request.

[v2 1/4] eglibc: fix builds on fedora 17 alpha

[nitin.a.kamble]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

Generally distros keep perl at /sur/bin/perl
Fedora 17 alpha also has /bin/perl

this causes eglibc build on such distros to put perl interpreter path in
the perl scripts as /bin/perl

But we set perl location for target as /usr/bin/perl

This mismatch of perl path causes failure of rootfs image creation
like this:

| error: Failed dependencies:
|       /bin/perl is needed by eglibc-utils-2.13-r23+svnr15508.i586
NOTE: package core-image-sato-1.0-r0: task do_rootfs: Failed
ERROR: Task 8
(/home/nitin/prj/poky.git/meta/recipes-sato/images/core-image-sato.bb,
do_rootfs) failed with exit code '1'

This Fixes bug : [YOCTO #2286]

I'd recommend something like:

sed -i -e '1s,#!.*perl,#! ${bindir}/perl,' ${D}${bindir}/mtrace 

which will only match on the first line and matches .*perl rather
than /bin/perl.

Cheers,

I found some other issues with this and the contents of the -nativesdk
eglibc-utils package. I've merged an updated version which uses
${bindir}/env perl and hardcodes /usr/bin/env in the -nativesdk case
(which is an assumption nativesdk makes in general).

Cheers,

[v2 2/4] grub-1.99: use gcc-cross for building the target binaries

[nitin.a.kamble]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

It was using distro gcc to build binaries for target. This got detected
on fedora 17 alpha, on which it hit an gcc-4.7 issue.

This Fixes Bug: [Yocto #2291]

More information in the patch header

Thanks to Saul Wold for suggesting to remove the --target parameter from
EXTRA_OECONF var.

to `__enable_execute_stack()'
