The following two fixes are needed to get glibc compile on alpha. The
first one is a 3.4/unit-at-a-time problem where a variable is only
used by asm and optimized out without the attribute, the second one
contains an extraneous line (fixed for nptl, broken in linuxthreads).
Ok to commit?

* sysdeps/alpha/fpu/e_sqrt.c: Mark as used.

* sysdeps/alpha/elf/pt-initfini.c (__asm__): Remove extra
.prologue.
