Need to change the method for determining the number of CPUs on Linux
https://bugs.webkit.org/show_bug.cgi?id=273675
Reviewed by Carlos Garcia Campos.
Try to use sysconf(_SC_NPROCESSORS_ONLN) on Linux to determine the
amount of usable CPU cores. While Perl provides access to the function
in its POSIX module, the _SC_NPROCESSORS_ONLN constant is not defined
and the value of the constant is used instead. Using the value is fine
as it is part of the user space API and not expected to ever change.
As a fallback, make Perl parse /proc/cpuinfo directly instead of
shelling out to a cat|grep pipeline: Perl knows how to regex and how
to count just fine.
* Tools/Scripts/webkitdirs.pm:
(determineNumberOfCPUs): Replace usage of nproc command with sysconf,
update /proc/cpuinfo parsing fallback.
