[Gcl-devel] [PATCH 00/11] Add support for AArch64

[Will Newton]

This patch series allows building gcl on AArch64. The series is ordered
roughly in order of patch quality, with the final patch being a hack
to #ifdef out some x86 code that presumably should be #ifdefed in a
more subtle manner.

Most of the patches are not AArch64 specific but are general issues that
I hit during the porting process. I was building with gcc 4.8 on Ubuntu
Trusty.

The port requires using --enable-dlopen --disable-custreloc as the
branch range on AArch64 is +/-128MB and the heap soon gets too large
to branch between the loaded code objects. The maxpage tweak was an
effort to avoid that issue but it just delayed the inevitable.
