handle letter 'y'.
(arm_elf_section_letter) : Declare it.
* config/tc-arm.c (arm_elf_section_letter): Handle letter 'y' to set
SHF_ARM_NOREAD section flag.
* doc/c-arm.texi (ARM section attribute 'y'): Document it.
gas/testsuite/ChangeLog:
* gas/arm/section-execute-only.s: New test case.
* gas/arm/section-execute-only.d: Expected output.
