It is fully reproducible on a quad-core mips system, with the same
error:

[...]
[  2%] Generating ../all.h
Generating ../all.h
cp: cannot create regular file `/srv/ths/debian/mscore/mscore-0.9.2+dfsg/build/all.h': File exists
make[4]: *** [all.h] Error 1
[...]

Apparently the cmake build system in mscore isn't safe for parallel
make runs. The mips/mipsel buildds are dualcores, I figure this makes
them less likely to trip up on this (the mipsel build went ok).

I forced the CPUS detection in debian/patches/08-multiple-jobs.dpatch
to 1, this way mscore builds fine on the same machine.
