Build failure in 4.4 branch with --enable-ext-google-docs on Xubuntu 14.04 amd64: "undefined reference to symbol 'dlclose@@GLIBC_2.2.5'"

(originally filed as Bug 87293, but I was redirected here)


I am attempting to build with the Google Drive connection:
./autogen.sh --enable-ext-google-docs --with-gdrive-client-secret ; make

This is happening consistently for me, building latest libreoffice-4-4
from git, if I use --enable-ext-google-docs at all:

...

make[1]: *** [/home/fun/libreoffice/workdir/LinkTarget/Executable/icontest]

make: *** [build] Error 2


The build completes successfully on master (although in that case,
Google Drive doesn't show up as a CMIS option). The above error
happens trying to build libreoffice-4-4 for the past few days.

If I build 4.4 with just ./autogen.sh ; make then it builds.

I'm running an up-to-date Xubuntu 14.04 amd64.

If you could assist, that would be most helpful :-)


(I really, really want an LO that will connect to GDrive
transparently. The Windows build of 4.3 or 4.4beta1 connect and works
fine on Windows 7, but fail in Linux under Wine, for which I've filed
https://bugs.winehq.org/show_bug.cgi?id=37674 .)
