[PATCH] D23729: [compiler-rt] Use flags found when configuring builtins during compilation

[Francis Ricci via llvm-commits]

fjricci added a comment.

This change breaks on certain sysroots, because of `-ffreestanding`. I removed that flag in https://reviews.llvm.org/rL279496, after verifying that the non-standalone build also doesn't add this flag by default.
