[PATCH 0/1] Fix perl-native compilation on ubuntu 11.04

[Khem Raj]

Ubuntu decided to move libc and friends to /usr/lib/$ARCH-linux-gnu
so we need to know that in perl's configure

[PATCH 1/1] perl-native_5.12.2.bb: Fix compliation on ubuntu 11.04-alpha

[Khem Raj]

Ubuntu has moved eglibc to /usr/lib/${arch}-linux-gnu and
/lib/${arch}-linux-gnu so we need that to be added to glibpth in
Configure.

Currently we set LD=ld in environment for recipes inheriting native
class. This overrides the LD settings in the Makefiles of perl and
it tries to link by calling ld which does not work since its using
-l<x> on commandline and ubuntu linker seems not to look into
the new location for these libraries. Its better to use gcc for linking
here anyway

We have CCLD for when we want to use CC as our LD (and yes, this usually 
just ends up as CC, but lets be clear please).

Agreed, I've merged this patch but with the tweak from Tom.

This change is not working for me on Ubuntu 11.04 {released}.
The libraries are found in /lib/i386-linux-gnu and /usr/lib/i386-linux-gnu
At least on the machine where it fails, uname -m gives i686, so the test
   >> ++test -f /usr/lib/`uname -m`-linux-gnu/libc.so&& glibpth="/usr/lib/`uname -m`-linux-gnu $glibpth"
fails.

I hard coded the i386-linux-gnu paths and was able to build perl-native on Ubuntu 11.04

I used uname since I thought that was way to make it common for both x86_64
and x86 but it seems they made life harder than that. I did not have
32bit installation to verify

Note: no criticism intended :-)

Perhaps some sort of wildcard could work?  Just replace `uname -m` with "*"?
I just tried this here and it seems to work on my x86 system.
   $ test -f /usr/lib/*-linux-gnu/libc.so && glibpth="/usr/lib/*-linux-gnu $glibpth"
   $ echo $glibpth
   /usr/lib/i386-linux-gnu
