That's right.
It has been written in README file of makedumpfile:
002: makedumpfile is compiled with -static option, because the command should
run while the second kernel, which may not mount root filesystem and may
not contain dynamic library files, is running.
If the dynamic library files, which are needed by makedumpfile, exist
while the second kernel is running, we can remove -static option from
Makefile. This is a workaround for some linux distributions which does
not contain static library files needed by makedumpfile.
