The actual intention is that no dynamic relocation exists. However, some GNU ld ports produce unneeded R_*_NONE. (If a port is not care enough to determine the exact .rel[a].dyn size, the trailing zeros become R_*_NONE relocations. E.g. powerpc64le ld as of 2.38 has the issue with defconfig.) R_*_NONE are generally no-op in the dynamic loaders. So just ignore them. With the change, we can remove ARCH_REL_TYPE_ABS. ARCH_REL_TYPE_ABS is a bit misnomer as ports may check RELAVETIVE/GLOB_DAT/JUMP_SLOT which are not called "absolute relocations". (The patch is motivated by the arm64 port missing R_AARCH64_RELATIVE.) While here, replace "egrep" with "grep" as "egrep" is deprecated in GNU grep 3.7.
