[Intel-gfx] [PATCH i-g-t] tests/gem_concurrent.c: rename to gem_concurrent_all

Wed Apr 1 08:36:59 PDT 2015
From: Tim Gore <tim.gore at intel.com>
Recent patch #7763349a9a87.. renamed gem_concurrent_blit.c
to gem_concurrent.c and then added entries to Makefile.am
to make two identical executeables (but with different
names) from this source file. This executeable changes its
behaviour based on argv[0]. But, this has broken the
Android build, which does not use autotools.
This patch instead renames the source file to match
the name of one executable (gem_concurrent_all.c) and
creates a second source file which simply #includes the
first. The Makefile.am entries are also removed.
This restores the simple test.c -> test executeable
relationship seen in the rest of IGT and allows the
Android build system to work without parsing Makfile.am
or having to incorporate a special workaround for this
test.
