xtensa: add config option to disable linker relaxation
The default linker behavior is to optimize identical literal values and remove unnecessary overhead from assembler-generated "longcall" sequences to reduce code size. Provide an option to disable this behavior to improve compile time. Signed-off-by: Chris Zankel <chris@zankel.net>

+ help
+ Enable this function to disable link-time optimizations.
+ The default linker behavior is to combine identical literal
+ values to reduce code size and remove unnecessary overhead from
+ assembler-generated 'longcall' sequences.
+ Enabling this option improves the link time but increases the
+ code size, and possibly execution time.
