I am trying to build Julia on a computer that is new to me, using MKL (which I’ve never used before so maybe this isn’t the problem here). I ran `source /path/to/intel/bin/compilervars.sh intel64` and made this Make.user file

```julia
USE_BINARYBUILDER=0
USE_INTEL_MKL = 1

```

Not a lot of bells and whistles there, but I thought that was all I needed. It goes along for quite some time until it hits this error, which I can’t find on the internet anywhere:

```julia
In file included from src/s_fmax.c:32:
src/fpmath.h:109: error: duplicate member ‘manl’

                 from src/s_fmax.c:33:

make: *** [julia-deps] Error 2

```

It looks similar to what’s going on here: [build failing on MSYS2 build · Issue #6234 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/6234), but I can’t find a workaround from that.

Has anyone run into this before or know what to do in this situation?
