Can you post your nsswitch.conf?  I don't normally use nss_mysql, but
I just installed it on my box to see what an strace ls would reveal,
and it does not show libmysql being accessed when files appears first
for passwd, shadow, and groups.

carcharias ~ # grep -e ^passwd -e ^shadow -e ^group /etc/nsswitch.conf
passwd:      files mysql
shadow:      files mysql
group:       files mysql
carcharias ~ # strace -f -e open -o /tmp/strace.out ls -l / >/dev/null
carcharias ~ # grep mysql /tmp/strace.out
carcharias ~ # vi /etc/nsswitch.conf
carcharias ~ # grep -e ^passwd -e ^shadow -e ^group /etc/nsswitch.conf
passwd:      mysql files
shadow:      mysql files
group:       mysql files
carcharias ~ # strace -f -e open -o /tmp/strace.out ls -l / >/dev/null
carcharias ~ # grep mysql /tmp/strace.out

Also the outputs of emerge --info and emerge -pv sys-libs/glibc might help.
