H.J. Lu 8c31902cff x86/boot: Double BOOT_HEAP_SIZE to 64KB 
When decompressing kernel image during x86 bootup, malloc memory
for ELF program headers may run out of heap space, which leads
to system halt.  This patch doubles BOOT_HEAP_SIZE to 64KB.

Tested with 32-bit kernel which failed to boot without this patch.
