[Libreoffice] ~2x faster gnumake ...

Hi there,

        Weelll ... nicer structures aside; having put a breakpoint in stat64
( catch syscall stat64 FWIW ;-) - I discovered that the vast majority of
our stats were not from 'stat' at all (which clearly has been optimised
heavily) - but instead from 'glob':

        read.c (parse_file_seq) calls glob on all dependencies.

        For each of those it does a stat ;-)

        make -sr before:

real    0m5.795s
user    0m3.513s
sys     0m2.274s

        make -sr passing 'PARSEFS_NOGLOB' to the beastie[1]

real    0m2.496s
user    0m2.342s
sys     0m0.150s

        Which essentially killed the system component of performance, and saved
a truck-load of system calls ;-)

        I'll do some more poking around to make it an up-stream-able, robust
patch.

        ATB,

                Michael.

[1] - un-conditionally breaking globbing for sure but - why not ? :-)
