#10 fix arm 32 linker script

[James Bottomley]

The arm 32 linker script fails for complex binaries (usually static data arrays with strings) because it doesn't gather all the .data. sections and the compiler will emit some even without -fdata-sections. The diff fixes this and also adds a .bss. gather just in case -fdata-sections is used.
