dave@mx3210:~/gnu/gcc/objdir/hppa-linux-gnu/libgfortran/.libs$ nm libgfortran.a
|grep _gfortran_specific__sqrt_
00000000 T _gfortran_specific__sqrt_r4
00000000 T _gfortran_specific__sqrt_c4
00000000 T _gfortran_specific__sqrt_c8

I don't fully trust the kernel on this system.  I see in config.h:

/* libm includes sqrt */
/* #undef HAVE_SQRT */

I think the configure test probably failed due to a cache management problem,
although I didn't see anything the the system log.
