CMake has no table mapping to these flags automatically, but if you set 
them up yourself CMake will not change them.  Any link library option 
beginning with a "-" is left untouched, so you can do something like

SET(MYLIB my_static_lib)
IF("${CMAKE_SYSTEM}" MATCHES IRIX)
   SET(MYLIB -Wl,-all -lmy_static_lib -Wl,-notall)
ENDIF("${CMAKE_SYSTEM}" MATCHES IRIX)
#...
TARGET_LINK_LIBRARIES(my_shared_lib ${MYLIB})
