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 2019-01-23 19:30:07 +01:00			`.global __rpx_start`
