Subject: [libc] Add a simple linux aarch64 config.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1f567b2c6f6573b19cbd81f876717f28623b51e9;p=platform%2Fupstream%2Fllvm.git

[libc] Add a simple linux aarch64 config.

Summary:
With this change, "ninja check-libc" on linux/aarch64 succeeds.

However, all entrypoints with machine dependent implementations
have been skipped. A good number of these skipped entrypoints can
be enabled once we have aarch64 syscall support available.
