valgrind: Fix ptest build with musl

musl unearthed a problem when building out of tree, config.h was being
used from $(srcdir) instead of generated config.h in $(builddir)
this assumed functions e.g. mallinfo() and more which are not in musl
as a result tests broke.

Also add fixes to build remaining tests when building on musl

pass -fno-pie as it cant use PIE especially in ptests/x86_64
