Cannot build latest krb5 on Mac 10.9

[Weijun Wang]

Hi All

I just git cloned krb5 from github and cannot build it on my OS X 10.9 
with Xcode 5. The error is

ld: warning: ignoring file builtin/aes/iaesx64.so, file was built for 
unsupported file format ( 0x7F 0x45 0x4C 0x46 0x02 0x01 0x01 0x00 0x00 
0x00 0x00 0x00 0x00 0x00 0x00 0x00 ) which is not the architecture being 
linked (x86_64): builtin/aes/iaesx64.so

The so files in builtin/aes are

$ file lib/crypto/builtin/aes/*.so
lib/crypto/builtin/aes/aescrypt.so: Mach-O 64-bit object x86_64
lib/crypto/builtin/aes/aeskey.so:   Mach-O 64-bit object x86_64
lib/crypto/builtin/aes/aestab.so:   Mach-O 64-bit object x86_64
lib/crypto/builtin/aes/iaesx64.so:  ELF 64-bit LSB relocatable, x86-64, 
version 1 (SYSV), not stripped

So this iaesx64.so has a different arch. Could that be the problem?

Thanks
