[Buildroot] mstpd install location

[Colin Foster]

Hello,

I'm finally getting mstpd to start working in buildroot. I noticed two
blockers:

mstpd was running "pidof -c" while busybox doesn't support the -c
option. As a result, mstpd would fail entirely. I'm working with mstpd
to either remove the -c option if it isn't necessary, or detect
capabilities.

Also, the bridge-stp script gets called by the kernel, and needs to be
in /sbin. However, the install directory is /usr/sbin. I'm confused,
since Makefile.in seems to use $(DESTDIR)/sbin.

It seems there are two options:
1. Change the install directory of mstpd to /sbin, or
2. Add a post-install hook to soft link /sbin files to
/usr/sbin/{mstpd,mstpctl,bridge-stp}

I'm not familiar with autotools-package, so I'm not sure why option 1
isn't already happening. If option 1 couldn't, or shouldn't happen, I
can certainly look into implementing option 2.


Any feedback is appreciated.
