Unconditional, because it doesn't contain an override like e.g.
SRC_URI_append_beagleboard does.

Yes. I think that += is easier to use and less error-prone.

- As Koen already pointed out, it adds whitespace automatically, so in
whitespace separated lists like SRC_URI you don't have to care.

- You can use multiple statements in a recipe.

SRC_URI += "foo"
SRC_URI += "bar"

vs.

SRC_URI_append = " foo"
SRC_URI_append = " bar"

The latter wouldn't work.

In the case of gcc, I modified SRC_URI in some inc file resulting in
"... file://my.patchfile://fortran-cross-compile-hack.patch ...".

SRC_URI_append = "file://fixup.patch" is probably a bad example.
