wrapping memory functions

[ceotto]

Hi.
I'm starting a new project using Arduino MKR1000 card (SAMD) and RTOS is a great starting point to avoid the development of lots of low level useless code. Thank you for the work in this porting, perhaps I'm going to contribute as far as I can.

Obviously all the memory has to be managed by the RTOS so I putted the file platform.local.txt in the porting directory (\arduino-1.8.9\portable\packages\arduino\hardware\samd\1.8.1).

I've found that in the file platform.local.txt there is a typo, the following lines (39 & 40):
undefined reference to '__wrap_malloc'
undefined reference to '__wrap_free'
has to be changed into:
# undefined reference to '__wrap_malloc'
# undefined reference to '__wrap_free'
to make the compiler work.

I was able to setup and test the examples of the release 8 (so the RTOS appears to work in Genuino MKR1000).
Now I'm going to download and test the RTOS10 porting.
Best regards
