Example:

$ ./mach build toolkit/library/symverscript -v
 0:00.26 /usr/bin/make -C toolkit/library -j4 BUILD_VERBOSE_LOG=1 symverscript
 0:00.27 make: Entering directory '/home/glandium/gecko/obj-x86_64-pc-linux-gnu/toolkit/library'

$ rm obj-x86_64-pc-linux-gnu/toolkit/library/symverscript
$ ./mach build toolkit/library/symverscript -v
 0:00.26 /usr/bin/make -C toolkit/library -j4 BUILD_VERBOSE_LOG=1 symverscript
 0:00.27 make: Entering directory '/home/glandium/gecko/obj-x86_64-pc-linux-gnu/toolkit/library'
 0:00.27 make: 'symverscript' is up to date.
 0:00.27 make: Leaving directory '/home/glandium/gecko/obj-x86_64-pc-linux-gnu/toolkit/library'

That can be quite confusing.
