  To: buildroot; +Cc: Julien Olivain, Fabrice Fontaine

Fix the following build failure without MMU:

/home/buildroot/autobuild/instance-1/output-1/host/riscv64-buildroot-linux-uclibc/bin/ld.real: test_fork.o: in function `.L6':
test_fork.c:(.text+0x120): undefined reference to `fork'

autobuilder failure is raised since the addition of RISC-V support by
commit c789bcddf0fb17580bef0cdc45b5334a90ecdf13

Fixes:
