But then you will have two PKGBUILDs that only differ by few lines
within the build() function, and two separate repositories to support
them. They are not two different packages, they are the same package
but compiled differently. I think it makes sence to have one PKGBUILD
that can procude different packages, and they have to conflict with
each other to make sure someone does not install both at the same
time. If tools cannot handle it then tools should be modified to allow
for this workflow.

just my two cents.
