[Buildroot] Bash string manipulation in Kconfig

[Stefan Fröberg]

Hello everyone.

What is the equivalent buildroot thing for handling the following bash
string stuff ?

FULL_DOWNLOAD_URL="http://www.somedomain.com/blah/blah2/blahblahblah/somefile"
FILE=${FULL_DOWNLOAD_URL##*/}
echo ${FILE}

That will correctly print only the last part of the url, "somefile"

But how to do similar in buildroot  .mk files ???

Best regards
Stefan
