Subject: [PATCH] Mark .rodata section as read only in COFF object file

.rodata directive from GAS assembly produces .rodata as read/write for COFF
object file by default (object file format for Windows), but read only for
ELF. This change marks it as read only explicitly for COFF.

The issue happens when building Chromium for Windows ARM64, with FFmpeg.
