glibc_2.1-3: two tiny debian/rules patches

[Gordon Matzigkeit <gord@trick.fig.org>]

There are two problems with the debian/rules file in glibc_2.1-3:

1) configure should not depend on patched-stamp, because the sources
   may not yet be unpacked.

2) Since Marcus Brinkmann's build/host architecture policy proposal
   is in progress, the rules file should check DEB_HOST_ARCH, as well
   as the ARCH environment variable:

# New cross-compilation policy may set the DEB_HOST_ARCH variable.
ifdef DEB_HOST_ARCH
ARCH := $(DEB_HOST_ARCH)
else
 # dpkg-cross sets the ARCH environment variable, so use it.
 ifdef ARCH
 ARCH := $(ARCH)
 else
 ARCH := $(BUILD_ARCH)
 endif
endif

Thanks!
