Rather than fork+exec:ing a whole bash process for every file of
interest, split up the work into ${PARALLEL_JOBS} separate file lists,
and then fork off a single worker per list.
Since workers now run in a fork, we also don't have to re-parse the
arguments on every call to patch_file().
In the worker, we also add a low-overhead check for the ELF magic,
which allows us to skip all non-ELFs without having to fork off
additional processes. In the event that we encounter an invalid ELF,
that is still taken care of by the existing exitcode-test in
patch_file().
On a 4-core/8-thread box, this cuts down the time it takes to fix the
RPATHS in the host directory from around 25s to 1.5s.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
