Make ICU assembly portable to ARM

Make ICU assembly portable to ARM

This patch fixes the following error:

  CC src/out/Release/obj/third_party/icu/linux/icudt42l_dat.o
  third_party/icu/linux/icudt42l_dat.s: Assembler messages:
  third_party/icu/linux/icudt42l_dat.s:5: Error: unrecognized symbol type ""
  make: *** [src/out/Release/obj/third_party/icu/linux/icudt42l_dat.o] Error 1

The problem is the assembly syntax that is used is not portable to ARM,
where the '@' symbol is a comment:

  > Note on targets where the @ character is the start of a comment
  > (eg ARM) then another character is used instead. For example the
  > ARM port uses the % character.

(from http://sourceware.org/binutils/docs-2.18/as/Section.html#Section)

Using % instead of @ appears to work on both ARM and x64.
