Don't make assumptions about usable memory.
...
When using a legacy BIOS, the memory regions used by the BIOS are well
defined. This is not the case when using a UEFI BIOS. So include the
stack area in the BSS so the loader knows how much memory to allocate,
and check we have space to relocate the program to either low or high
memory.
There are still some assumptions in the USB driver code that need to
be fixed.

Use 'size -B' instead of 'size -G' to determine BSS size.
...
The -G option is a relatively recent addition, so fails on older
systems (issue #11 ).
