3.4-stable review patch. If anyone has any objections, please let me know.

From: Mike Frysinger <vapier@gentoo.org>
commit 0be421862b857e61964435ffcaa7499cf77a5e5a upstream.
After commit ec2212088c42 ("Disintegrate asm/system.h for Alpha"), the fpu.h header which we install for userland started depending on special_insns.h which is not installed.
However, fpu.h only uses that for __KERNEL__ code, so protect the inclusion the same way to avoid build breakage in glibc:
/usr/include/asm/fpu.h:4:31: fatal error: asm/special_insns.h: No such file or directory
