It's a bug in your package.  Packages should not rely on anything in $HOME
for building, and should definitely not write anything to $HOME, as packages
are not supposed to modify anything outside of the build directory during
build.

The reason the mipsel buildd has a non-writable home is precisely because it
previously /did/ have a writable home, and various packages would in the
process of building pollute it with contents that would break subsequent
package builds.  This way, all packages that depend on reading from /or/
writing to $HOME break equally.
