Makefile: limit build targets for non-s390x architecture

Browse Source 
A subset of s390 tools can be useful on non-s390x architectures such as
x86 or arm. Limit the build targets for these architectures with
'pvattest' and 'libpv' as the first candidates.

A cross compilation on x86 for s390x will still build the entire package
provided that the HOST_ARCH variable is set properly:

$ make HOST_ARCH=s390x CROSS_COMPILE=s390x-linux-gnu-

Cross compilation on s390x for x86 will limit the build targets as
described:

$ make HOST_ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-
