insufficient fix for gcc localised output in stubdom makefile

[Guillaume Rousse <Guillaume.Rousse@inria.fr>]

Hello.

There was a slight change in stubdom makefile from 3.3 to 3.3.1, in 
order to use non-localised gcc output:
GCC_INSTALL = $(shell LANG=C gcc -print-search-dirs | sed -n -e 
's/install: \(.*\)/\1/p')

However, this is still unsuffient to just set LANG:
[guillomovitch@n2 xen]$ LANG=C gcc -print-search-dirs | sed -n -e 
's/install: \(.*\)/\1/p'

At least on our build system, you have to export LC_ALL instead:
[guillomovitch@n2 xen]$ LC_ALL=C gcc -print-search-dirs | sed -n -e 
's/install: \(.*\)/\1/p'
/usr/lib/gcc/i586-manbo-linux-gnu/4.3.2/
