Why do this, given:

+ lappend options "libs=-fgnu-runtime"

Note that the placement of -fgnu-runtime on the libs
flags is by design. Otherwise for those tests that
null out the compiler flags, the -fgnu-runtime flag
is lost.

Did you try:

lappend options "additional_flags=-fgnu-runtime"

? If not, try that.

Ah, I see Andrew has commented, his suggestion is reasonable, it is better to do this in the compiler.
