[OpenJDK 2D-Dev] RFR: 8220074: Clean up GCC 8.3 errors in LittleCMS

[Erik Joelsson]

Hello,

There is no need to do compiler version checks like this. We just add 
all the necessary warning disabling for all versions. GCC will not fail 
or warn for invalid -W-no... flags and we use this feature for this very 
reason. We don't think it's feasible to track warnings per compiler 
versions..
