removed support for 80bit FP type

compiler-rt/lib/Makefile-pnacl

 # This Makefile builds onacl version of libgcc.a
 #
 # More information on the functions of libgcc can be found at:
 # http://gcc.gnu.org/onlinedocs/gccint/Libgcc.html#Libgcc
 # ../README.txt
 #
 # The following variables are expected to be set externally:
 
 # SRC_DIR
 # CC
 # AR
 # CFLAGS
 
 # pick up .c files from another dir
 vpath %.c ${SRC_DIR}
 
 
 # TODO(robertm): augment/prune this as we gain a better understanding of llc

-# NOTE: for *division* we only use the pattern: div*i?.c
-#       excludes the float and complex versions

powitf2 appears to be in the 80 bit float category (just noticed it didn't have
a "ti" in name)
