sdk: do not exclude all doc directories

[mcprat]

this is untested but very simple fix...

bulldbot errors in building gettext using the sdk...

/builder/shared-workdir/build/sdk/staging_dir/host/share/gnulib/gnulib-tool: *** file /builder/shared-workdir/build/sdk/staging_dir/host/share/gnulib/doc/relocatable.texi not found
/builder/shared-workdir/build/sdk/staging_dir/host/share/gnulib/gnulib-tool: *** Stop.

Some packages which are using local gnulib source
are expecting files to exist in the directory:

staging_dir/host/share/gnulib/doc

so delete the other doc directories directly
instead of excluding all of them.

Fixes: d167adb ("gettext-full: bootstrap to local gnulib source")

@mpratt14 anyone confirming this works?

Builds fine on macOS 12.6.5. I selected WRT3200ACM, and everything from utils/coreutils. If you know what packages are affected, I can add them to the build and come back with results. I also updated my routers today: the latest master builds fine on both macOS and Linux. Targets: WRT3200ACM, x64, TL-WR1043NDv4.
Unrelated question: I have some private packages, where the sources are located on the local machine. Whenever I push anything to my fork, the build-bot tries to compile them and the build fails because the sources cannot be found. How do I exclude them from the build-bot?

@httpstorm remember this PR is for the sdk only

[mcprat]

anyone can verify by building the SDK and unpacking it and seeing that the file exists inside

staging_dir/host/share/gnulib/doc/relocatable.texi

if no one else tests this then I will soon but I'm busy right now

In that case I just cloned your fork and compiled the tools-gnulib-sdk branch. I don't know how to use any other SDK or build environment.

[mcprat]

make target/sdk/compile

and then the sdk will be in the bin directory somewhere

unpack it somewhere else and verify that it has the file

Nice feature. Thanks for explaining! It took only a few seconds to generate the SDK. It does have the file:
