dkms module build fail on "gcc: error trying to exec 'cc1': execvp: No such file or directory"

[fullmetal1]

When I try to install a kernel through MHM, the module rtl8822bu-dkms-git does not build. If I install the kernel directly through pacman, however, it works just fine.

From the MSM output

(2/5) Install DKMS modules
==> dkms install rtl8822bu/5.2.4_20170919 -k 4.16.2-1-MANJARO
Error! Bad return status for module build on kernel: 4.16.2-1-MANJARO (x86_64)
Consult /var/lib/dkms/rtl8822bu/5.2.4_20170919/build/make.log for more information.

and the contents of make.log
