hv: riscv: specifiy -fpie / -fno-pie explicitly

Browse Source 
Without -fpie or -fno-pie specified in the CFLAGS and ASFLAGS, different
versions of riscv64-linux-gnu-gcc have different behavior, for example,
Ubuntu 13.3.0-6ubuntu2~24.04 will compile as if -fpie, but 15.1.0 will
compile as if -fno-pie. To make the build consistent specify -fpie when
CONFIG_RELOC=y and -fno-pie otherwize explicitly.
