[PATCH] Prevent appending "-g" after "-g3" to compile options in info-macros.exp.

[Andreas Arnez <arnez@linux.vnet.ibm.com>]

When upstream gcc is given a command line with "-g3" followed by "-g",
it doesn't generate a ".debug_macro" section.  This is because the last
option wins, thus downgrading the debug level again.  Without any macro
debug information in the executable, info-macros.exp obviously yields
many failures.

Since "-g" is appended by DejaGnu's target_compile whenever the "debug"
option is set, the fix just removes that option.

	* gdb.base/info-macros.exp: Remove "debug" from the compile
	options.
