Since commit 247ef2a fio has optional libiscsi engine support
This patch enables fio iscsi support if BR2_PACKAGE_LIBISCSI
was selected, which also requires pkg-config as it is used by the
configure script to detect libiscsi.
There is no --disable-libscsi option in the configure script: if
--enable-libiscsi is not passed, it doesn't even try to detect/use
libiscsi.
