+The standard variable passed to make for an alternate installation

+This patch helps to integrate libdfp downstream.

+Subject: [PATCH] powerpc: Ignore tests that are known to fail on soft-dfp and
+ POWER hard-dfp
+
+The test tests/test-cast-to-underflow has 36 known failures.
+The fix for these failures are being tracked at PRs #32, #71 and #84.
+Having these failures makes it hard for newcomers, downstream and
+continuous integration systems to detect when a failure is already known
+or not.
+This patch ignores the 36 tests known to fail on soft-dfp and POWER
+hard-dfp.  It affects only ppc, ppc64 and ppc64le.

+    invocation of "make check".
+    
+    This patch creates one <test-name>.test-result file per test
+    with an indication like PASS or FAIL.  Furthermore the file tests.sum
+    is created with one line per test in order to indicate the test result.
+    
+    At the end of "make check" the failing tests are listed and the
+    corresponding out files are dumped.
+    
+    This way you'll get an indication of failing tests even if you can
+    just view the log file instead of having access to the build-directory.
+    
+    The scripts and some parts of the Makefile comes from glibc in order to
+    be more equal.
+    
+    This change also allows to mark an test as:
+    -XFAIL or XPASS: Add a Makefile variable like test-xfail-<testname> = yes.
+    -UNSUPPORTED: The testcase has to return with exit-code 77.
