Subject: llvm: enable LLVMgold.so build by adding binutils dependency
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ed5e8d08803098aa0f5d991057392b99ad075e2;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

llvm: enable LLVMgold.so build by adding binutils dependency

Currently, LLVMgold.so is not built because the binutils headers
are missing during the build process.

This allows LLVM to find the necessary headers and build the LLVMgold.so,
which is required for Link Time Optimization (LTO) support properly.
