Sequentialize install targets in debug_and_release builds

Browse Source 
Debug/release install targets can potentially install the same files which
leads to errors on install when running make with -j > 1.

If build_all is set, make the 'install' dependent of the new target
'debug-release-install' which contains the commands of 'debug-install' and
'release-install'.

Of course, debug/release is not hard-coded, but the content of the BUILDS
variable is used.
