PATCH: attribute used for dllname

[Marcus Meissner]

Hi,

When used with -funit-at-a-time optimization, "static const char foo[];" 
is optimized away without reference in the file.

Since without stub functions the only reference is within an asm() statement
the compiler thinks it is used and throws it away.

Ciao, Marcus

Changelog:
	Used __attribute__((used)) on dllname, or newer gcc optimizations
	throw dllname away.
