toolchain: uClibc: fix compile with full language support enabled (fixes #13095)

When building with CONFIG_BUILD_NLS=y, uClibc fails to compile with following
message (or similar, according to https://dev.openwrt.org/ticket/13095):

This seems to also depend on the host system used, e.g. running a fresh
checkout on a Debian 7.6 system triggered this error, while running the
very same stuff on an Ubuntu 12.10 Quantal Quetzal does not trigger it.

This is the configuration I used:

-snip-
buildbot@buildbot:~/openwrt-nls.git$ scripts/diffconfig.sh
CONFIG_TARGET_ar71xx=y
CONFIG_TARGET_ar71xx_generic=y
CONFIG_TARGET_ar71xx_generic_Default=y
CONFIG_DEVEL=y
CONFIG_BUILD_NLS=y
CONFIG_DOWNLOAD_FOLDER="/srv/downloads/downloads"

In the ticket mentioned above, a patch is referenced which solves this issue.

Note, that this issue is also present on 14.07.
