[linux-lvm] patch to fix segfault complaints.

[Jim Cromie]

others have noted various segfaults,
ex:

>>vgextend -- extending volume group "vg01" by physical volume
"/dev/hde1"
>>in kernel
>>Segmentation fault (core dumped)


This patch fixes configure script to build good (no segfault) lvm tools
for me
theres probably a more comprehensive way to do this, ymmv.

note also that Im only checking for 2.96, not 2.96-85.  this may or may
not matter
