nolibc changes for 7.2

Highlights:
* New architectures: OpenRISC and 32-bit parisc
* New library functionality: alloca(), assert(), creat() and ftruncate()
* Automatic large file support
* Proper 64-bit system call argument passing on x32 and MIPS N32
* Cleanups of the testmatrix
* Various bugfixes and cleanups
