Fix build on OpenBSD/mips64 (#638)

The build fails on OpenBSD/mips64 because clang 11's integrated
assembler expects read-only .eh_frame:

../src/mips/n32.S:585:9: error: changed section flags for .eh_frame, expected: 0x2
        .section .eh_frame,"aw",@progbits
        ^

Use EH_FRAME_FLAGS to get matching flags for the section.
