The /lib/firmware directory contains random firmware for various
devices. It happens that some of them might be or appear to be ELF
files, but they shouldn't be checked by fix-rpath. For example, one of
the Qualcomm VPU firmware file appears to be an ELF file, but patchelf
isn't happy about it:
$ ./output/host/bin/patchelf --print-rpath output/target/lib/firmware/qcom/venus-4.2/venus.b00
patchelf: patchelf.cc:387: void ElfFile<Elf_Ehdr, Elf_Phdr, Elf_Shdr, Elf_Addr, Elf_Off, Elf_Dyn, Elf_Sym>::parse() [with Elf_Ehdr = Elf32_Ehdr; Elf_Phdr = Elf32_Phdr; Elf_Shdr = Elf32_Shdr; Elf_Addr = unsigned int; Elf_Off = unsigned int; Elf_Dyn = Elf32_Dyn; Elf_Sym = Elf32_Sym]: Assertion `shstrtabIndex < shdrs.size()' failed.
Aborted (core dumped)
Even though patchelf definitely shouldn't crash, it anyway doesn't
make sense to check ELF files in /lib/firmware, so let's exclude this
directory from our check.
