Enable hardware acceleration for ARMv8 targets.
When ARMv8 hardware acceleration is enabled on AArch64 without any
additional flags, the build fails with the following messages:

make[3]: *** [Makefile:3801: wolfcrypt/src/port/arm/src_libwolfssl_la-armv8-aes.lo] Error 1
This is because of some inline assembly in parts of the AES structure
using the "m" constraint.
So lets use the flag -mstrict-align to prevent this error.

[Thomas: restrict the -mstrict-align workaround to AArch64, as ARMv8-A
can also be used in an AArch32 build, and in this case, gcc doesn't
support the -mstrict-align flag]

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 Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
