Targets: Freescale KSDK - extern } syntax error fix
Fixed linker files (Ram size on one) and for the rest increased the heap and stack size
With the old logic if Serial::writeable() was called before and/or used to block calls to Serial::putc() it would never write due to EVENT_TXDRDY trailing a write to TXD. Add a dummy write to TXD before pins are connected to the peripheral. This primes the EVENT_TXDRDY to lead future writes rather than trail. Since STOPTX isn't used this seems safe.
