gcc: fix incorrect handling of the comparison arguments
This patch fixes compiler error during libbroadvoice build.
The comparison arguments where not correctly handled.
The fix is done in development tree:
https://github.com/foss-for-synopsys-dwc-arc-processors/gcc/commit/b4035128ba8f8bbbf9527f54f261a87b304ca4c5
and will be a part of the next release of ARC GNU tools.
Once that new release happens this patch must be removed.
Fixes:
