https://github.com/llvm/llvm-project/pull/126315 changes the premerge testing to build in Debug, Release, and MinSizeRel configs, as opposed to only MinSizeRel, but for some reason the matrix is not returning all options now. Fix so that it actually builds the intended configs. Per discussion in [146161](https://github.com/llvm/llvm-project/issues/146161), only test all three configs on Linux x86_64. Other OS's and configurations will build in Debug mode only. Also fix a cmake variable and remove outdated comments. Bug: https://github.com/llvm/llvm-project/issues/146161

# Libc's build is relatively small comparing with other components of LLVM.
|
|
# A fresh linux overlay takes about 180MiB of uncompressed disk space, which can
|
|
# be compressed into ~40MiB. MacOS and Windows overlay builds are less than 10MiB
|
|
# after compression. Limiting the cache size to 1G should be enough.
|
|
# Prefer sccache as it is modern and it has a guarantee to work with MSVC.
|
|
# Do not use direct GHAC access even though it is supported by sccache. GHAC rejects
|
|
# frequent small object writes.
