[libc-commits] [libc] [libc] Remove redundant file(COPY) for x86_64 types (PR #201317)

[Jeff Bailey via libc-commits]

https://github.com/kaladron created https://github.com/llvm/llvm-project/pull/201317

Removed the redundant file(COPY) command from the x86_64 architecture check in libc/include/llvm-libc-types/CMakeLists.txt.

This command eagerly copies the x86_64 directory to the binary directory, which is redundant because individual headers are already copied by their respective add_header targets. It also preserved read-only depot permissions from the source tree, making the build directory read-only and causing rm -rf to fail.

Assisted-by: Automated tooling, human reviewed.
