• Fixes a spurious warning, improving the debugging experience for AIX 64-bit binaries.
• Silently ignores `_AUX_EXCEPT` entries, which BFD does not need to parse, simplifying the parser.

[PATCH v1] Fix wrong auxtype for storage class warning in AIX.

Aditya Vidyadhar Kamath submits a patch to resolve a spurious warning in BFD when debugging 64-bit AIX binaries. The warning, ‘wrong auxtype … for storage class’, occurred because BFD’s _bfd_xcoff64_swap_aux_in() function did not properly handle the _AUX_EXCEPT auxiliary entry, which is used for functions with exception tables. The fix modifies the function to silently skip _AUX_EXCEPT entries, as BFD does not need to parse their payload, thus eliminating the warning.
