[OE-core] [PATCH V3] gcc: Do not use --with-linker-hash-style if LINKER_HASH_STYLE is empty

[Khem Raj]

We allow to set LINKER_HASH_STYLE to be empty so this would fail
since --with-linker-hash-style needs an argument and cant be empty

Changes in v3:
- Fix typo in gcc option

Changes in v2:
- Use inline if statement instead of old syntax
