The link command is:

arm-rtems6-gcc testsuites/fstests/fserror/test.c.113.o 
-o/home/kinsey/rtems-development/rtems-ddci/build/arm/deos/testsuites/fstests/imfs_fserror.exe 
-Wl,-Bstatic -L. -ltestimfs -lrtemstest -lrtemscpu -lrtemsbsp 
-Wl,-Bdynamic -qrtems -march=armv7-a -mfpu=neon -mfloat-abi=hard -mthumb 
-gdwarf-2 -fPIC -Wl,--gc-sections 
-L/home/kinsey/rtems-development/rtems-ddci/bsps/arm/shared/start 
-L/home/kinsey/rtems-development/rtems-ddci/bsps/arm/deos/start 
-Wl,-call_shared -Wl,-no-undefined /desk/arm/lib/libkernel.so 
/desk/arm/lib/libdeos653pal.so -L/desk/arm/appbin -ltime-prl -lface653 
-lgcc-so -Wl,--wrap=printf -Wl,--wrap=puts -Wl,--wrap=putchar


The newly introduced linking flags toward the end are:

-Wl,-call_shared -Wl,-no-undefined /desk/arm/lib/libkernel.so 
/desk/arm/lib/libdeos653pal.so -L/desk/arm/appbin -ltime-prl -lface653 
-lgcc-so


The first error is:

/home/kinsey/rtems-development/tools/lib/gcc/arm-rtems6/10.3.1/../../../../arm-rtems6/bin/ld: 
./librtemscpu.a(threadsetstate.c.59.o): in function 
`_Thread_Scheduler_get_home':
/home/kinsey/rtems-development/rtems-ddci/build/arm/deos/../../../cpukit/include/rtems/score/threadimpl.h:1533: 
undefined reference to `_Scheduler_Table'
