This changes the initialisation of output sections so that it is possible to create read-only sections fed only from linker script BYTE, SHORT, LONG or QUAD. That currently isn't possible even for one of the well-known ELF sections like .rodata, because once a section is marked read/write that sticks. On the other hand if we start read-only, well-known ELF sections end up read/write as appropriate. For example .tdata will still be SHF_ALLOC + SHF_WRITE + SHF_TLS. PR 26378 * ldlang.c (map_input_to_output_sections): Start with a read-only section for data statements. * testsuite/ld-elf/size-2.d: Adjust to suit.
