[Xen-devel] [PATCH] autoconf: exec_prefix should default to $prefix not $ac_default_prefix

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Otherwise "./configure --prefix=/usr" still ends up with exec_prefix=/usr/local
and therefore LIBDIR, PRIVATE_PREFIX and PRIVATE_BINDIR still point to
/usr/local/foo.

This was broken in 54f28913a2b3 "autoconf: xen: move standard path variables to
config/Paths.mk.in" which tried to add code to expand exec_prefix earlier.
