Bug#944319: lld-9: please package development headers

[Shawn Landden]

Package: lld-9
Severity: wishlist

Zig lang (https://ziglang.org) wants to link against liblld and needs development headers to do so.
Until these are packaged zig has to build its internal version of lld, which is identical to upstream lld.
