_eglGetConfigAttrib is for API level usage. Since we know the attribs
are valid we can use _eglGetConfigKey().
Thus all the validation (as done in the former) and error checking
here can be dropped.
Taking it a step further I'd drop the struct and directly use the
values from _eglGetConfigKey().

We don't need to walk through the list twice. Simply pass the config
(to be printed) to _eglPrintConfig()?
Plus we can drop the temporary printMsg all together.

I'd fold the two functions _eglPrintConfigs and eglPrintConfigDebug.
Might even swap the EGL_CONFIG_DEBUG_OPTION enum with "print_chosen"
or equivalent bool.
With my nitpicking, the resulting code should be around half the size ;-)
