Fix definition of ESYSROOT to use SYSROOT's prefix

For a given location, we were basing ESYSROOT on the prefix of that
location instead of the prefix used by the SYSROOT location. For
example, if BROOT=/foo, ROOT=/bar, EPREFIX=/baz, EROOT=/bar/baz, and
SYSROOT=/ then ESYSROOT should be /foo, not /baz.
