Is there any specific function symbol we can test for in that library?
If it exports something like socket() or connect() on SVR4, we can make
configure probe for that instead of blindly including the library.

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

[7]       STRSZ       0x1229
[8]       SYMENT      0x10
[9]       PLTGOT      0xec2c
[10]      PLTSZ       0x4b8
[11]      PLTREL      0x11
[12]      JMPREL      0x36d0
[13]      REL         0x34e8
[14]      RELSZ       0x1e8
.....

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