[Bug 1274723] [NEW] go programs operate in "32-bit" allocation mode

[Michael Hudson-Doyle]

Public bug reported:

I am having long and interesting conversations with upstream about how
to fix this properly, but we also need a fix in time for trusty.  The
symptoms of this problem is that programs occasionally die with messages
like:

runtime: memory allocated by OS (0x7f67005000) not in usable range
[0x8b00000,0x88b00000)

I think the fix is just changing malloc.goc to put the heap at an
address that is available to user space processes on linux aarch64.

** Affects: gcc-4.8 (Ubuntu)
     Importance: Undecided
         Status: New
