Subject: build: copy contents of 'src' folder to build dirs (if present)
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7c8c3226dc8ecd2b77d1d1e8215e0fbb52819cd7;p=openwrt%2Fstaging%2Fblocktrron.git

build: copy contents of 'src' folder to build dirs (if present)

The normal Prepare step for a build is unpack, apply patches.
But for certain packages, patches contain whole files, which
would be nice to have separately and copied over as a last step
in the Prepare phase.

We need it for some other packages + patches, but I think
the 'hostapd' package can be used as a test for this.

As a quick note:
the reason the condition is being evaluated as
`[ ! -d ./src/ ] || $(CP) ./src/* $(HOST_BUILD_DIR)`
and not with
`[ -d ./src/ ] && $(CP) ./src/* $(HOST_BUILD_DIR)`
is that the latter would translate in a build failure if the `src`
folder is not present (the exit code would be 1).
The first one, succeeds for both cases (if `src` present or not).
