[dpdk-dev] [PATCH v2 0/5] small cleanup and fixes

[Bruce Richardson]

Made some small changes to meson to shorten the code and increase
readability. While testing, found a number of issues on FreeBSD builds,
which are fixed in this set too.

Bruce Richardson (5):
  build: simplify subdirectory detection for EAL
  build: increase readability via shortcut variables
  distributor: skip building if power library not found
  examples/l2fwd-cat: fix build on FreeBSD
  devtools/test-meson-builds: fix support for FreeBSD

[dpdk-dev] [PATCH v2 1/5] build: simplify subdirectory detection for EAL

[Bruce Richardson]

Within EAL we had a series of if statements for selecting the EAL directory
to use. Now that the directory names match those of the OS's they are for
we can instead just use a generated subdirectory name, shortening the code.
To avoid strange errors, we still need to check for unsupported OS's, but
do this check up-front in the config meson.build file.

[dpdk-dev] [PATCH v2 2/5] build: increase readability via shortcut variables

[Bruce Richardson]

Define variables for "is_linux", "is_freebsd" and "is_windows"
to make the code shorter for comparisons and more readable.

[dpdk-dev] [PATCH v2 3/5] distributor: skip building if power library not found

The power library is not built on non-Linux systems, so skip the
distributor sample if it's not found, as it's a mandatory dependency.

I think this is a bash option.
We may require bash at the top of this script as a workaround.
Or we can revert the inital patch piping to cat for verbose mode.

Probably best to do the latter, I think. No real need to have two verbose
modes, just one. Let me see what I can do, if there may be any other
options.
