04a65a183b xlat/gen.sh: speedup xlat generation 
This commit implements the following changes:
- increases the number of concurrent jobs to twice the CPU count;
- creates a circular buffer, so instead of running multiple jobs
  at once, the generator tries to keep about the same number of jobs
  being run concurrently;
- runs gen_git and gen_make concurrently in order to squeeze in
  one more bit of concurrency.

With my deeply scientific measurements, this approach achieves
up to 15% speedup with dash and about 30-40% with bash as /bin/sh
on a 4-core machine.

* xlat/gen.sh (main): Declare pids local variable, append pid of every
run job to it; increase the limit of jobs to ncpus * 2; when the limit
is reached, wait for the first pid in pids instead of resetting jobs
to zero and waiting for all the run jobs; put gen_git and gen_make
into background.

48cb6336d8 tests: update futex test to accommodate the recent kernel change 
Kernel commit v4.14-rc1~162^2~8 refactored futex implementation and
introduced checks for invalid shift sizes.  Accommodate this change
by allowing EINVAL in the corresponding futex checks.

* tests/futex.c (CHECK_FUTEX_GENERIC): Reset errno before the syscall.
(main) <wake_ops>: Add err2 field, describe err/err2 fields.
Add EINVAL as a possible errno to the checks that contain invalid
shift values.
Update return value check so it checks that values are strictly
as expected.

55bc4164bd maint: generate ioctl entries without target architecture code execution 
ioctls_sym.sh used to generate and invoke target architecture
executables that limited its applicability.

from the dwarf sections.
This approach allows to generate ioctl entries for any target
architecture supported by compiler.
