[Buildroot] [git commit branch/2021.02.x] package/coremark-pro: disable parallel build

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=bd84c189b5c2047a2be4c1816710af751ba98521
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

Disable parallel build as it seems to be totally broken:

/bin/bash: line 0: cd: /home/buildroot/autobuild/instance-2/output-1/build/coremark-pro-1.1.2743/builds/linux64/gcc64/obj/bench/core: No such file or directory

/bin/sh: 1: cd: can't cd to /home/buildroot/autobuild/instance-1/output-1/build/coremark-pro-1.1.2743/builds/linux/gcc/obj/bench/fp/loops/SP
