File fix_discards_qualifiers_warning.patch of Package open-vm-tools.7780

This patch is required in SLES11 environments which will report the following
error during compilation:

 cert_key.c: In function 'LoadOpenSSLConf':
 cert_key.c:264: error: passing argument 1 of 'ASN1_STRING_set_default_mask_asc'
   discards qualifiers from pointer target type

In order to avoid the warning, mask must be passed as a char to 
 ASN1_STRING_set_default_mask_asc.
