libclc.patch (llvm 11.0.0)
libclc is part of the LLVM repo now, the separate mirror is no longer updated.
Versioning is quite confusing: pkg-config version is stuck at 0.2.0, the tag from the mirror was 0.4.0, but now it's in LLVM so it follows LLVM.
The python2 based build system is dropped: https://github.com/llvm/llvm-project/commit/d6e0e6d255a7d54a3873b7a5d048eee00ef6bb6d#diff-eadd7e7d6ad9e3f2b2ca4010924946948dac2350f8b901e9744c10a79ecdb92e
The attached patch builds libclc from llvm-project 11.0.0, using CMake.
(also resets BROKEN_powerpc64 because let's try again)
Clover must be rebuilt (PORTREVISION bumped) when switching to this version, since the directory for the bytecode files has moved from lib to share, and apparently clover gets this path compiled in via headers or something.
