dpkg: Avoid automatic target architecture detection

dpkg is using a script (dpkg-architecture.pl) to detect the target
architecture automatically.
Unfortunately, it is using the cross compiler prefix to do the detection
and for ARM, oe-core is using <vendor>-linux-gnueabi for toolchains with
and without call-convention hard. The script then always detects
'armel' and never gets 'armhf' for call-convention hard.

This solves:
dpkg: error processing archive evtest_1.32+0+b8343ec112-r0_armhf.deb (--install):
 package architecture (armhf) does not match system (armel)
 Errors were encountered while processing:
 evtest_1.32+0+b8343ec112-r0_armhf.deb
