cookie_io fixes for gcc-5.3

twoerner · twoerner · commit a5641ab63ec1 · 2016-06-17T10:31:56.000-04:00
Using the latest (as of today) gcc-arm-embedded toolchain caused two build
failures similar to:

	error: unknown type name 'cookie_io_functions_t'

These custom IO functions are now protected by a define, so define _GNU_SOURCE
which enables all such areas. This is a libc issue.
