Compact casesi patterns don't have a reload version. This causes build
failures of "trousers" package for ARC.
Current patch disables compact casesi patterns for ARCv1 (750D and 770D)
via passing "-mno-compact-casesi" option when compiling "trousers".
This change is a temporary workaround and the feature is going to be
fixed in the next ARC toolchain release version.
