Valgrind availability

[Marcin Juszkiewicz]

Hi

During last few days I fetched over 26 thousand of Fedora package 
repositories. Plan to go though all spec files and submit some patches 
mainly related to my aarch64 work.

But there is one thing I want to note:

%ifarch %{ix86} x86_64
BuildRequires: valgrind
%endif

Currently there is only one architecture in Fedora which does not have 
Valgrind support and it is s390 (32-bit s/390). x86(-64) has it, arm32 
and aarch64 have them, ppc64(le) has it too.

So if your package build depends on Valgrind (or valgrind-devel) please 
consider change to:

%ifnarch s390
BuildRequires: valgrind
%endif

I know that some maintainers do not like to look at their packages on 
architectures other than x86(-64) because they do not own hardware, do 
not like being hit by bugs in valgrind or have other excuses. If you are 
one of them then please add a note to spec file about. Check "cscppc" 
package for example.

Sure, some packages may fail due to bug in valgrind implementation on 
some secondary architecture. But then we can notify developers so it 
will get improved (while in same time package may get this build 
dependency disabled for a while).
