> 26 checking how to hardcode library paths into programs... immediate

This is just a shell switch statement so it does not do much.

> 23 checking whether the C compiler works... yes

This is done by default by normal autoconf and caching it does not help because
the newly build gcc might not work.

Anyways caching won't help cross builds here.

Basically each library that uses libtool does this.  Each multilib could use
its own cache instead of each library which would improve this.  But with -j48,
the time spent in configure scripts is minor still.
