gdbarch_init called for core files, too?

[Jason R Thorpe]

So, I'm seeing alpha_gdbarch_init() called twice if I do:

	gdb foo foo.core

...the first time, alpha_abi is correctly set to ALPHA_ABI_NETBSD, but
the second time it gets ALPHA_ABI_UNKNOWN.  This means that the wrong
target-dependent info is being used while debugging the core file.

This behavior is ... counter-intuitive.  Why is gdbarch_init being called
for the core file?  Should't it be sufficient to initialize it based on
the program corresponding to the core file?

...or should I make the code that looks for ABI tags in note sections to
also look for "NetBSD-CORE" notes, too?
