stdlib: add missing features to build PolarSSL
This patch adds the missing features to the C library included
in the Trusted Firmware to build PolarSSL:
- strcasecmp() function
- exit() function
- sscanf()* function
- time.h header file (and its dependencies)
* NOTE: the sscanf() function is not a real implementation. It just
returns the number of expected arguments by counting the number of
'%' characters present in the formar string. This return value is
good enough for PolarSSL because during the certificate parsing
only the return value is checked. The certificate validity period
is ignored.
