Configure error grep illegal option q

[petk]

Description

The following code:

./buildconf
./configure

Resulted in this output:

...
checking whether we are using musl libc... grep: illegal option -- q
Usage: grep -hblcnsviw pattern file . . .
no
...

But I expected this output instead:

checking whether we are using musl libc... no
