libqb fails to cross build from source, because it uses an uncached
AC_RUN_IFELSE for determining whether CLOCK_MONOTONIC works. That check
is flawed in that availability of CLOCK_MONOTONIC is a runtime property
and may change from system to system.
The attached patch makes it check whether CLOCK_MONOTONIC is declared
and only then try whether it works. In case of cross compilation,
CLOCK_MONOTONIC is assumed to work if available, which seems like a
reasonable guess to me.
After applying the patch, libqb cross builds successfully. Can you take
it?
