[OE-core] [PATCH 1/4] conf, recipes: Add new variable LINKER_HASH_STYLE

[Khem Raj]

LINKER_HASH_STYLE in OE is set to either 'sysv' or 'gnu'
depending upon processor architecture e.g. mips does not support
gnu hash style so is uses sysv

besides 'sysv' and 'gnu' third option is to set it to 'both' we do
not do that by default but user can still set it
