perf tools: Fix python extension build
commit 67d5268908283c187e0a460048a423256c2fb288 upstream.
The util/python-ext-sources file contains source files required to build
the python extension relative to $(srctree)/tools/perf,
Such a file path $(FILE).c is handed over to the python extension build
system, which builds the final object in the
$(PYTHON_EXTBUILD)/tmp/$(FILE).o path.
After the build is done all files from $(PYTHON_EXTBUILD)lib/ are
carried as the result binaries.
Above system fails when we add source file relative to ../lib, which we
do for:
../lib/bitmap.c
../lib/find_bit.c
../lib/hweight.c
../lib/rbtree.c
All above objects will be built like:
$(PYTHON_EXTBUILD)/tmp/../lib/bitmap.c
$(PYTHON_EXTBUILD)/tmp/../lib/find_bit.c
$(PYTHON_EXTBUILD)/tmp/../lib/hweight.c
$(PYTHON_EXTBUILD)/tmp/../lib/rbtree.c
which accidentally happens to be final library path:
$(PYTHON_EXTBUILD)/lib/
Changing setup.py to pass full paths of source files to Extension build
class and thus keep all built objects under $(PYTHON_EXTBUILD)tmp
directory.
