AVR32: Build position-independent u-boot
Add -fPIC -mno-init-got to the avr32-specific CFLAGS to make u-boot position independent. This will make relocation a lot easier. -mno-init-got means that gcc shouldn't emit code to load the GOT address into r6 in every function prologue. We do it once and for all in the early startup assembly code, so enabling this option makes u-boot a bit faster and smaller. The assembly parts have always been position-independent, so no code changes should be necessary. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
