fa1c077b41
This patch removes the ability to build the runtimes in the 32 bit multilib configuration, i.e. using -m32. Instead of doing this, one should cross-compile the runtimes for the appropriate target triple, like we do for all other triples. As it stands, -m32 has several issues, which all seem to be related to the fact that it's not well supported by the operating systems that libc++ support. The simplest path towards fixing this is to remove support for the configuration, which is also the best course of action if there is little interest for keeping that configuration. If there is a desire to keep this configuration around, we'll need to do some work to figure out the underlying issues and fix them. Differential Revision: https://reviews.llvm.org/D114473
