Re: [openssl.org #2795] openssl-1.0.1a - undefined symbol: OPENSSL_ia32cap_P with ultrasparc cpus (solution inside)

Hi,

 i got following error, when building the new openssl-1.0.1a package on a Sun 
 Solaris 10 operation system with an UltraSPARC cpu:

I figured out that the bottom of 
openssl-1.0.1-a/crypto/evp/e_rc4_hmac_md5.c  was modified in 1.0.1a and 
utilizes the non-existing OPENSSL_ia32cap_P. 

I quickly looked into the code and made following patch:

This fixed the compilation issue on Non-Intel/AMD cpus
