package/ola: fix check for google.protobuf
Fix the google.protobuf check in an upstreamable way. As suggested by Arnout, use an autoconf ac_cv_have_* variable so we can pass it on the command line. This is generic behaviour for a lot of autoconf internals, so it makes sense to do it this way. Signed-off-by: "Yann E.

-configure: do not check for google.protobuf

-The check for google.protobuf is inherently flawed for cross-compilation,
-as it uses the host Python to check for target modules.
-
-In Buildroot, our dependencies ensures that google.protobuf is present
-by the time we configure and build ola, so we can just skip the test
-altogether.
-
-We don't need to fake the result of the test: it is used nowhere; the
-test is only here to fail or succeed.

+
+ configure: add option for user to override checks for Python modules
+
+ The check for google.protobuf is inherently flawed for cross-compilation,
+ as it uses the host Python to check for target modules.
+
+ In this case, it is not possible to check for a Pyhon modules altogether,
+ and we need to rely on the user to properly tell us whether we do or do
+ not have google.protobuf.
+
+ This is done by adding am autoconf cache variable:
+ ac_cv_have_pymod_google_protobuf
+
+ which can be set to:
+ - yes : force the test to be true
+ - no : force the test to be false
+ - (empty) : let the test decide
+
+ This is then used in AX_PYTHON_MODULE to override the test.
+
+ Currently, only the google.protobuf Python module is checked for, but
+ the same could be done later on of other Python modules that may be
+ added in the future, of course.
+
+ Fixes configure-errors like:
+ http://autobuild.buildroot.net/results/e63/e634d5f0cee3967caffaa6e7ada8c0968e3eff63/build-end.log
+
+ Also fixes some under-quotation in the python module check.
