there aren't any configure flags or runtime knobs that i know of on the glibc 
side of things.  you could edit elf/dl-support.c and try commenting out the 
parts that handle AT_SYSINFO and AT_SYSINFO_EHDR.  or edit 
sysdeps/unix/sysv/linux/x86_64/gettimeofday.c and force it to always use the 
syscall version at the end of the file.

or upgrade your kernel to one that isn't buggy :p
