Please take a look at
	pkgsrc/audio/cdparanoia/patches/patch-ae (search for "dispcache")
	pkgsrc/sysutils/xbatt/patches/patch-ab   (first hunk)

I found and fixed them since I tested them on a.out toolchain.

If a program is only tested on ELF toolchain, the quality of code
is like this.

ELF has other too unique features (ex. C symbols and assembler symbols
are same, dynamic linker automatically loads dependent libraries),
which make it easy to write non-portable programs.

I don't think that the layout of initialized data can be re-arranged
in linker stage.

~300KB is not acceptable in the HEAD?

Mmm, gas / may not be acceptable....
