[Bug libc/7104] New: strtol result is not always needed.

["dfs1122 at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

Version: 2.8~20080505-0ubuntu7

warning: ignoring return value of 'strtol', declared with attribute
warn_unused_result

strtol has useful side-effects that do not require examination of the result. 
For example, (void)strtol(string,&string,0) will skip an unneeded number in string.

Suggest warn_unused_result is not applied to strtol and family.
