Bug#834144: llvm-3.8-dev: please add symlink from ./build to ../share and ../lib etc

[Ximin Luo]

Package: llvm-3.8-dev
Version: 1:3.8.1-8
Severity: wishlist

Dear Maintainer,

Some software like compiler-rt expect --obj-root to contain the other
directories like lib/ and share/. Take for example

https://github.com/llvm-mirror/compiler-rt/blob/release_39/CMakeLists.txt#L57

as well as an older version (currently in-use in rust-stable)

https://github.com/rust-lang/compiler-rt/blob/rust-2016-04-04/CMakeLists.txt#L109

In both cases, LLVM_BINARY_DIR is actually --obj-root as can be seen from earlier in the file.

Since Debian puts --obj-root in build/, then for the above assumptions to work
build/ must contain symlinks to the other directories. It already contains ../include
so the ones missing are ../lib and ../share.

For now I will have to patch rustc in my local builds, but fixing this bug would
make that unnecessary for the next release.
