Build errors makefiles WSL in llvm

[obiwanjacobi]

I got build errors using makefiles under WSL.
[disclaimer] I'm a noob trying this for the first time.

My Command Line:

cmake -G "Unix Makefiles" ../llvm
make -j 10

Result - fine up to 98%:

collect2: fatal error: ld terminated with signal 11 [Segmentation fault], core dumped
compilation terminated.

Not sure were core dumps end up...

I also hit this on wsl2. Same linker errors looks like in the same targets as well. I found that dropping -j to around 2 seems to fix it but is very slow.

I haven't tried using lld yet.
