[Pkg-php-pecl] Bug#764047: uprofiler: FTBFS on non-x86: uses x86 assembly (rdtsc)

[Aaron M. Ucko]

Source: uprofiler
Version: 0.11.0~20140929+d6495abf-1
Severity: important
Justification: fails to build from source

Builds of uprofiler for non-x86 architectures have been failing with
errors of the form

  /«BUILDDIR»/uprofiler-0.11.0~20140929+d6495abf/extension/uprofiler.c:973:3: error: impossible constraint in 'asm'
     asm volatile("rdtsc" : "=a" (__a), "=d" (__d));

or

  Error: unrecognized opcode `rdtsc'

depending on the architecture.

If you can reasonably make it function usefully beyond x86, please do
so; otherwise, please officially constrain its architecture list to

  any-i386 any-x32 any-x86_64

Thanks!
