    * lib/target-supports.exp: 
ÂÂÂÂÂÂÂÂAdd effective-target keywords "trampolines" and 
	"int_larger_than_16_bits".
	Add avr-*-*, hppa2.0w-hp-hpux11.23 and hppa64-hp-hpux11.23
	to the list of targets without trampoline support.
ÂÂÂÂÂÂÂÂAdd "avr-*-*" to the list of targets without support for profiling.
