[OE-core] [PATCH 1/5] conf,recipes: Redefine LINKER_HASH_STYLE

[Khem Raj]

LINKER_HASH_STYLE is not set to either sysv or gnu
depending upon architecture e.g. mips does not support
gnu hash style among the supported architectures so
we make sure its set to 'sysv' form mips

Linker flags are munged to adhere to renamed variable

Third option is to set it to 'both' we do
not do that by default but user can still set it
