Teensy 3 / FastLED linker error

[Genoil]

#include <FastLED.h>

void setup() { 
    Serial.begin(2000000);
    //Serial.println("fix");

    CRGBArray<10> leds;
    FastLED.addLeds<NEOPIXEL, 3>(leds, 10); 
}

void loop() { 
}

Produces:

/Applications/Teensyduino.app/Contents/Java/hardware/tools/arm/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/lib/armv7e-m/fpu/libc.a(lib_a-writer.o): In function `_write_r':
writer.c:(.text._write_r+0x12): undefined reference to `_write'

The problem is triggered by FastLED.addLeds.

Removing the line comment before the Serial.println("fix") fixes this. Strange...

This is a much better fix:
Teensy.mk, instead of defining these as OTHER_LIBS, just add them to LD_FLAGS. Now FastLED builds without the println required, AND the binary size is about 60K smaller. Another issue, where I had to remove new.cpp in teensy3/cores from the build process, is also fixed with this change:

LDFLAGS+= $(call PARSE_BOARD,$(BOARD_TAG),build.flags.libs)
