kumquat-buildroot/package/gcc/arc-2014.08/100-libstdcxx-uclibc-c99.patch
Alexey Brodkin a484a6ca2c ARC: bump tools to 2014.08 release 
Now when new shiny tools are released by Synopsys we're ready for version
update in Buildroot.

Important change in this release is switching to combined "binutils-gdb" repo
in accordance to upstream move.

Following patch now is a part of the most recent relese:
e6ab8cac62

So dropping it.
package/binutils/arc-4.8-R3/0001-arc-Honor-DESTDIR-in-custom-Makefile.patch

Since arc-2014.08 tools are still based on GCC 4.8 following patch is still
relevant so moving to the new folder to matxh ARC gcc bump.
package/gcc/arc-4.8-R3/100-libstdcxx-uclibc-c99.patch ->
package/gcc/arc-2014.08/100-libstdcxx-uclibc-c99.patch

Allow C99-depending features of libstdc++ with uClibc
The libstdc++ code is fairly restrictive on how it checks for C99
compatibility: it requires *complete* C99 support to enable certain
features. For example, uClibc provides a good number of C99 features,
but not C99 complex number support. For this reason, libstdc++
completely disables many the standard C++ methods that can in fact
work because uClibc provides the necessary functions.
This patch is similar and highly inspired from
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
a way that doesn't involve changing the configure.ac script, as
autoreconfiguring gcc is complicated. It simply relies on the fact
that uClibc defines the __UCLIBC__ definition.
