riscv: kexec: Remove -fPIE for PURGATORY_CFLAGS
With CONFIG_RELOCATABLE enabled, KBUILD_CFLAGS had a -fPIE option
and then the purgatory/string.o was built to reference _ctype symbol
via R_RISCV_GOT_HI20 relocations which can't be handled by purgatory.
As a consequence, the kernel failed kexec_load_file() with:
[ 880.386562] kexec_image: The entry point of kernel at 0x80200000
[ 880.388650] kexec_image: Unknown rela relocation: 20
[ 880.389173] kexec_image: Error loading purgatory ret=-8
So remove the -fPIE option for PURGATORY_CFLAGS to generate
R_RISCV_PCREL_HI20 relocations type making puragtory work as it was.
