Compiling the linux package (5.3.7-arch1-2-ARCH) via makepkg with distcc enabled in /etc/makepkg.conf fails to distribute out jobs via distcc as it should. By contrast, I can compile the linux source without makepkg using distcc and jobs are distrubuted out via distcc as expected.

I am thinking that there must be something in makepkg itself or within its helper scripts that is causing the failure. I am not expert but it seem that /usr/share/makepkg/buildenv/compiler.sh is asking the build to use distcc via a PATH modification which could be to blame.

For example, to mimic makepkg's call to distcc I did this experiment from the shell and confirmed that it does NOT work with distcc:
% export DISTCC_HOSTS="localhost/9 10.9.8.112/5"
% export PATH="/usr/lib/distcc/bin:$PATH"
% make -j15 bzImage

By contrast, from the distcc man page, I used this stanza and it does work as expected:
% export DISTCC_HOSTS="localhost/9 10.9.8.112/5"
% make -j15 bzImage CC=distcc


I attached:
* The makepkg.conf I am using
* A log showing the errors from the makepkg build
* A distccd log on the volunteer machine also showing errors that are not present when building without makepkg

Please let me know what else I can provide.
