[Bug nscd/10314] New: nscd fails to link when configuring with --disable-hidden-plt

[ura+bz at soum dot co dot jp]

I tried building glibc-2.10.1 with disable-hidden-plt configure option, nscd
failed to link due to the following error:

Then don't use the option.  This is why the Makefile rules are what they are.

I see, but I need glibc with --disable-hidden-plt.

I found the cause of this link error. The cause is the "atrribute_hidden" in
the declaration of "__nss_next2()" occurres. The link successes by appling
the following patch.
