libsocket requires libnsl:
$ dump -Lv /usr/lib/libsocket.so|more
/usr/lib/libsocket.so:
**** DYNAMIC SECTION INFORMATION ****
[INDEX] Tag Value
.dynamic:
[1] NEEDED /usr/lib/libnsl.so.1
[2] INIT 0xba30
[3] SONAME /usr/lib/libsocket.so.2
[4] HASH 0xa0

[11] PLTREL 0x11

.....
So, Is there a configure check for stuff like that?
