Bug#920594: papi: please make the build reproducible

[Chris Lamb <lamby@debian.org>]

Source: papi
Version: 5.6.0+git99-gd5a1a9ae2-1
Severity: wishlist
Tags: patch
User: reproducible-builds@lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that papi could not be built reproducibly.

This is because it encodes the build path when "helpfully" writing
the build CFLAGS to the example Makefiles:

 -CFLAGS	= -g -O2 -ffile-prefix-map=/build/1st/papi-5.6.0+git99-gd5a1a9ae2=. 
 +CFLAGS	= -g -O2 -ffile-prefix-map=/build/papi-5.6.0+git99-gd5a1a9ae2/2nd=. 

Patch attached.
