That's not a problem -- crash just needs to be compiled with "make lzo",
which will add these lines to the CFLAGS.extra and LDFLAGS.extra files:

  -DLZO     in the CFLAGS.extra file
  -llzo2    in the LDFLAGS.extra file

and will delete diskdump.o.  The subsequent rebuild will recompile
diskdump.c with lzo compression support.  You only have to enter
"make lzo" once, as it's effect is sticky.

This also requires the lzo, lzo-minilzo and lzo-devel packages to
be installed so that the lzo compression library can get compiled in.
But in your case, you would need to have the static versions of the
lzo and lzo-minilzo packages.
