[OE-core] [PATCH 1/1] linux-libc-headers: do_install: fix "Argument list too long" error

[Robert Yang]

There would be an "Argument list too long" error when the TMPDIR is in a deep
dir, for example, when "len(readlink -f TMPDIR) >= 350 (our supported value is
410)". Use "$(foreach ,,$(shell echo))" to fix it.

[YOCTO #5138]
