[Buildroot] [git commit branch/2020.11.x] package/makedumpfile: fix build on sparc64

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=89898b69916bac61bcf571bef103c43ada82d52e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.11.x

Fix the following build failure on sparc64:

/home/giuliobenetti/autobuild/run/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/sparc64-buildroot-linux-gnu/9.3.0/../../../../sparc64-buildroot-linux-gnu/bin/ld: /tmp/ccylTux8.o: in function `find_kaslr_offsets':
/home/giuliobenetti/autobuild/run/instance-0/output-1/build/makedumpfile-1.6.8/makedumpfile.c:4017: undefined reference to `get_kaslr_offset'

Even if this build failure is only raised with version 1.6.8,
get_kaslr_offset was also undeclared on sparc64 in version 1.6.7

Fixes:
