LU-3953 build: cache the results of configure between runs
This modification allow configure script cache the results of
heavy (required compilation) configure tests run on this system
so they can be shared between configure scripts and configure
runs, see configure's option --config-cache. This is very useful
for several configurations on the same machine with different
--enable/disable options.
The time of first clean pass:
time ./configure -C
real 1m9.879s
user 0m33.390s
sys 0m30.392s
The time of second pass with cached results:
time ./configure -C
real 0m10.190s
user 0m2.900s
sys 0m4.832s
