wut/libraries/wutcrt/crt0_rpx.s
fincs ee3bb10df4 First pass at adopting a devkitPro-style build system, see details:
- Added wut_rules and wut/rpx/rpl.specs to share/
- Replaced wut's CMake-based buildsystem with a standard Makefile
- Conflated all wut libraries into a single libwut.a library
- wut's old buildsystems (CMake & plain make) are broken as a result,
  this will be fixed in the future
- Docs, tests and samples are not buildable either at the moment
- wutcrt/wutnewlib:
  - RPX start function is __rpx_start, while RPL is __rpl_start
  - __init/fini_wut_* functions are no longer weak
  - __init_wut/__fini_wut are instead weak
  - Removed _exit implementation
  - exit syscall now points to _Exit instead of pointing to itself
- wutstdc++:
  - Renamed .cc files to .cpp
  - Temporarily disabled, due to an issue that will be addressed shortly
- wutdevoptab:
  - Fixed uninitialized variable warnings in __wut_fs_read/write
