Subject: nvme: add optional udev support
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c0293c3cc9f99b81c78ed193a7ce6187c6c4c78d;p=buildroot.git

nvme: add optional udev support

Commands like 'nvme list' require libudev but support for libudev is
decided at compile time, and in buildroot this is hard disabled.
Add a check for udev and if it is available build nvme with udev
support.

[Thomas:
 - add comment to explain the LIBUDEV variable value
 - use += instead of = to assign <pkg>_MAKE_OPTS.]
