Makefile: Replace the way to test if a string is empty
The output of command below,
# i386-elf-nm build/cbfs/fallback/romstage_null.offenders | \
grep -q "" ; echo $?
has different result on MacOS, OS X Mavericks, which outputs 0.
On linux, it outputs 1.
I assume it is misleading to search an empty string in a empty
string. Change it to testing if the string is empty.
