make build/install world builds 32bit libraries without request

[Mike Jakubik]

Hi,

I am updating a 5.4 system to 6-stable, and i noticed that buildworld is 
building 32bit compatible libraries, as seen below:

cc -m32 -march=athlon-xp -msse2 -mfancy-math-387 -DCOMPAT_32BIT  
-I/usr/obj/usr/src/lib32/usr/include  
-L/usr/obj/usr/src/lib32/usr/lib32  -B/usr/obj/usr/src/lib32/usr/lib32 
-pg -O2 -fno-strict-aliasing -pipe -I/usr/src/lib/libc/include 
-I/usr/src/lib/libc/../../include -I/usr/src/lib/libc/i386 
-D__DBINTERFACE_PRIVATE -I/usr/src/lib/libc/../../contrib/gdtoa -DINET6 
-I/usr/obj/lib32/usr/src/lib/libc -DPOSIX_MISTAKE 
-I/usr/src/lib/libc/locale -DBROKEN_DES -DPORTMAP -DDES_BUILTIN 
-I/usr/src/lib/libc/rpc -DYP -DHESIOD -Wsystem-headers -Werror -Wall 
-Wno-format-y2k -Wno-uninitialized -c /usr/src/lib/libc/net/getifaddrs.c 
-o getifaddrs.po

Why is it doing this? I have not specified that i want or need any 32bit 
compatibility.
