Otherwise on at least x86_64 and s390x there is an unwanted PLT entry in libc.so when configured with --enable-fortify-source=3 and build with -Os. This is observed in elf/check-localplt Extra PLT reference: libc.so: __strcpy_chk The call to PLT entry is in inet/ruserpass.c. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
