[blfs-support] Make unexpectedly doing parallel install and failing.

[Ken Moffat]

I think I saw this on a few packages some months ago, but I've just
had 'make install' fail in v4l-utils:

libtool: install: (cd /scratch/working/v4l-utils-1.14.2/lib/libv4l2; /bin/sh "/scratch/working/v4l-utils-1.14.2/libtool" --silent --tag CC --tag disable-static --mode=relink gcc -O2 -march=native -avoid-version -module -shared -export-dynamic -o v4l2convert.la -rpath /usr/lib/libv4l v4l2convert_la-v4l2convert.lo libv4l2.la )
/usr/bin/ld: cannot find -lv4l2
collect2: error: ld returned 1 exit status

By the time the install stopped, that lib had been installed.

Looks simialr to

I removed the v4l libs which had been installed and retried, this
time forcing make -j1 for the install - success.

So, just another datapoint, with a reminder that if make install
ever does this to you, try running make -j1 install.
