PS2, Line 11: (binutils 2.3x)
Are you sure this is used with the main branch? I was told ChromeOS
always uses the newest toolchain (and hence we have to restrict
toolchain updates to the releases). binutils was updated to 2.40
a year ago.

PS2, Line 11: Default is 1024 bytes (1 KiB)
There was a comment on another change (CB:81678) stating that
SIZEOF() is returning 0 (with the old binutils). If that's the
case, 1KiB might not be enough (possibly depending on alignment).
