description:
make: reduce debug logging and memory allocation for ${:U...}

Expressions of the form ${:U...} are often generated by .for loops.
Since these expressions are not generated knowingly by the make user, do
not fill the debug log with them since that would interrupt the normal
reading flow of the -dv log for nested expressions.
