The FT32 binutils use a bias to distinguish between RAM and flash
addresses.
This fix adds an ASM_OUTPUT_SYMBOL_REF() that unbiases references to
RAM symbols.
Only references to RAM objects have the bias applied. Flash objects
(that is, objects in ADDR SPACE 1) are not biased, so for these no bias
should be applied. Likewise references in the gdb section need to use
the biased address, so references in debug sections are not unbiased.
