Subject: [PATCH] Support ROCKBOX_DIR in HibyOS hosted bootloader

Currently if you want to compile a bootloader like so:

$ ../tools/configure --rbdir=/.rockbox.aigoerosq --target=aigoerosq --type=b

This won't work because the bootloader is hard coded to look for the rockbox Linux binary in /.rockbox/rockbox.erosq regardless of what is specified by '--rbdir'.

This commit adds support for ROCKBOX_DIR in the hosted HibyOS bootloaders.

After compiling, they can be installed with adb via (for example):

adb push build/bootloader.erosq /usr/bin/bootloader.erosq
