[PATCH] Use section name in warnings in display_debug_loc

[Tom Tromey]

While looking at an apparently malformed executable with
"readelf --debug-dump=loc", I got this warning:

    readelf: ./main: Warning: There is a hole [0x89 - 0x95] in .debug_loc section.

However, the executable only has a .debug_loclists section.

This patch fixes the warning messages in display_debug_loc to use the
name of the section that is being processed.
