From: Haritha D <harithamma.d@xxxxxxx>
Since the z/OS linker does not support searching dynamic libraries,
and the current setting of CC_LD_DYNPATH results in a directory
to be supplied to the link step with no option as the suffix,
it causes a linker error because the z/OS LD linker
does not accept directories as input.
Therefore, we workaround this by adding the -L option.
And, Introduced z/OS (OS/390) as a platform in config.mak.uname
