emxomf truncates hashed symbols when converting .a to .lib

[Yuri Dario]

Very long c++ symbols, already hashed after .o generation, are re-hashed when .a import library is converted to .lib format. The new symbol has the same length of previous one, so this is not necessary, and triggers a bug, since import library has different names.

Fix: do not check for len if !_ is present in the last SYMBOL_HASH_LENGHT bytes

Maybe strncmp can be used to check exactly for the initial two bytes of hash.
