Is /mnt/C a FAT or NTFS filesystem? You should not try to compile anything at all from a FAT filesystem unless you know what you're doing.

Code:

root@ubuntu:/mnt/C/sourcefolder# /usr/bin/make -f debian/rules clean
dh_testdir
dh_testroot
rm -f build-stamp
rm -f debian/preinst
rm -f debian/postinst
rm -f debian/postrm
dh_clean

Code:

cofs1 /mnt/C cofs rw,nosuid,nodev,noexec 0 0
