[ptxdist] [PATCH 1/7] add fake build type to HOST_CROSS_AUTOCONF

["Andreas Bießmann" <andreas@biessmann.de>]

If we build a cross toolchain where build == host == target the resulting
tools lack the host-tripplet before the tool name.
This patch introduce a '--build' autoconf switch with guessed (and modified)
build host tripplet from ptxdist to supress the generic autoconf guessing
mechanism in respective tools.
