Subject: logging.bbclass: avoid bashism in bbdebug()
X-Git-Tag: lucaceresoli/bug-15201-perf-libtraceevent-missing~30050
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=25cb71799e72d4e0c4fe39653d8b84280d087372;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

logging.bbclass: avoid bashism in bbdebug()

Checking the bbdebug() debug level parameter with a regular
test expression only works in bash. Using tr to filter out
digits and then checking whether anything is left achieves
the same result and is more portable.
