[PATCH 10/17] bfd / PE/COFF / arm: permit SEC_READONLY

[Jan Beulich]

Without this, even the default .text section would end up with the
IMAGE_SCN_MEM_WRITE flag, which is clearly wrong. (Afaict the flag,
oddly enough, doesn't affect the final linked binary, so there likely
are more anomalies.)

This is just so the target won't need excluding in a forthcoming new
testcase, which uses the .rva directive.
