Extended Description

lib/Driver/ToolChains.cpp has some code for Linux distribution specific behavior and triplets -- but it's currently missing information about Mandriva and derived distributions (given they use unlisted triplets, this results in not finding crtbegin.o etc.)

This patch adds the triplets, distro detection, and some distro specific behavior (hash-style setting etc).

when trying to use an ASan suppressions file under Emscripten:  Even though it
would be considered OK by SUSv4, the Emscripten runtime states "We don't support
partial munmapping" (see
<emscripten-core/emscripten@f4115eb>
"Implement MAP_ANONYMOUS on top of malloc in STANDALONE_WASM mode (llvm#16289)").
