This param:

slows down the entire app (check() std.xml function) by 29x on test.
Is it useful to add it on default config? Probably if you use external
dl, you should add it...

Well dmd test.d calls
gcc test.o -o test -m64 -Xlinker -L/dmd/linux/lib64 -Xlinker
-L/dmd/linux/lib32 -Xlinker --no-warn-search-mismatch -Xlinker
--export-dynamic -lphobos2 -lpthread -lm -lrt
How about DMD passing --export-dynamic to GCC if -shared is passed to DMD?
