Subject: [PATCH] Altera NIOS2 support
Add simple nios2 configuration support.
* include/private/gcconfig.h (NIOS2): New macro.
* include/private/gcconfig.h (mach_type_known, CPP_WORDSZ, MACH_TYPE,
OS_TYPE, DYNAMIC_LOADING, _end, __data_start, DATASTART, DATAEND,
ALIGNMENT, HBLKSIZE, HBLKSIZE, LINUX_STACKBOTTOM, NO_GETCONTEXT):
Define for NIOS2.
