X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2b6a6d4199e4eed65f20351d077a04a7cf9da460;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

rust-llvm: Compile llvm to use dynamic libraries

Our main llvm recipe uses dynamic linking already but rust-llvm does not.
Enabling this significanly reduces the size of llvm-rust to about a third
of what it was, which is a bettter configuration for us leading to smaller
TMPDIR and sstate objects.
