Like la264 only has 40 effective bits of virtual address space.
When TRY_EMPTY_VM_SPACE is set to 0x8000000000, it just exceeds
the range of 40-bit virtual address, causing the mmap mapping
to fail, thus causing the pch function to fail. To be compatible
with this situation set the macro to 0x1000000000.
gcc/ChangeLog:
* config/host-linux.cc (TRY_EMPTY_VM_SPACE): Modify the value of
the macro to 0x1000000000.
