Actually $$< does not work within backquotes unless escaped as a less
legible \$\$<, and does not work properly at all within double quotes,
whether escaped or not.

Do you prefer that I change only the first $(obj)u-boot into \$\$< and
leave the second one untouched, or that I leave both $(obj)u-boot
instances as-is for the sake of homogeneity?
