[PATCH] ARC: Enable XSI math extensions in ARC defconfigs

[Vlad Zakharov]

This commit enables XSI math extensions to the ISO C standard (bessel).
We need this to be able to build mpv package as it uses functions from
this extensions.

As an example I can refer to buildroot autobuilds where mpv build is
failing when using prebuilt ARC toolchain (which in its turn uses uClibc
without XSI math extensions):
