Nigel Croxon ce7098fb52 Enable out-of-tree building
This patch enables building gnu-efi outside of the source tree.
That in turn enables building for multiple architectures in parallel.

The build directory is controlled by the OBJDIR make variable.  It
defaults to the value of ARCH, and can be overridden from the command
line.

This patch also cleans up some doubled slashes between INSTALLROOT
and PREFIX.
