[PATCH] objdump: restore quiet build output

[Arnd Bergmann]

After a recent sync-check.sh update, a 'make -s' build prints a
single line of output from the 'cd -' command:

    /git/linux/tools/objtool

This is clearly unintended, so revert back to a completely quiet
build by redirecting the cd output to /dev/null.

Fixes: 2ffd84ae973b ("objtool: Update sync-check.sh from perf's check-headers.sh")
