Generic gcc toolchain targeting arm-eabi(-none) should work.

https://github.com/lucretia/tamp gives you one example.

However, you need to tailor the linker scripts (.ld)
for your board. (Sometimes, even different projects
might need different linker scripts for the same board.)

I also recently got one Teensy 3.1 with MK20DX256
and I would recommend that stay away from it (unless you have
already bought one).

For example, it does not have JTAG debugging interface
and the programming the device happens with a special
software (GUI-only on Windows, Linux luckily has plain
command line interface also).

If you are interested in Freescale Cortex-Mx processors,
Freedom boards like FRDM-K20D50M[1] are better, imo.

Yours,
