I am building for ARM/uclibc, Angstrom 2007.12/2008.1, so this affects both,
 .dev and .stable, I would think that it may be a problem with perl on the 
host system.

uclibc.inc has this line:
configmangle = 's,^KERNEL_SOURCE=.*,KERNEL_SOURCE="${KERNEL_SOURCE}",g; \
        s,^KERNEL_HEADERS=.*,KERNEL_HEADERS="${KERNEL_HEADERS}",g; \
        s,^RUNTIME_PREFIX=.*,RUNTIME_PREFIX="/",g; \
        s,^DEVEL_PREFIX=.*,DEVEL_PREFIX="/${prefix}",g; \
        s,^SHARED_LIB_LOADER_PATH=.*,SHARED_LIB_LOADER_PATH="/lib",; \
        s,^SHARED_LIB_LOADER_PREFIX=.*,SHARED_LIB_LOADER_PREFIX="/lib",; \
        s,.*UCLIBC_HAS_WCHAR.*,UCLIBC_HAS_WCHAR=y,g; \
        ${@["s,.*UCLIBC_HAS_LOCALE.*,# UCLIBC_HAS_LOCALE is not set,;",
""][bb.data.getVar("USE_NLS", d, 1) == "yes"]}'

at a later point it gets processed with perl:
perl -i -p -e '${configmangle}' ${S}/.config

In my case (Fedora 6 and Fedora 7 hosts) it has no effect, meaning that even if
I set USE_NLS=yes - the UCLIBC_HAS_LOCALE setting is never set to "y" in
.config of uClibc.

I did try various things, the only solution that worked for me was to do it
with sed:

if test "x${@'%s' % bb.data.getVar('USE_NLS', d, 1)}" = "xyes"; then
   sed -i -e s:'.*UCLIBC_HAS_LOCALE.*':'UCLIBC_HAS_LOCALE=y':g ${S}/.config  
fi

I am sure there are better ways to do it, this is how it worked for me. I'll
attach the patch that I use to the PR.

Perl version on Fedora 7: 
This is perl, v5.8.8 built for x86_64-linux-thread-multi

version on Fedora 6:
Perl This is perl, v5.8.8 built for i386-linux-thread-multi
