"5729da1 fdo#42865: privatized unique empty string symbol" - change of addsym.awk breaks the build on Mac/PPC

[Christian Lohmaier]

Hi *,

The change
http://cgit.freedesktop.org/libreoffice/core/commit/?id=5729da18a1852d842bd7de05d9d7fdcbec1e9ad5

or more precise this part of it:

breaks the build on Mac/PPC at least in neon, bridges, remotebridges.
Or in other words probably everywhere where a map-file is used.

just the neon one pasted here as it is the same for all:
ld: symbols names listed in -exported_symbols_list:
../../../../../unxmacxp.pro/misc/exports_neon.map not in linked
objects
__ZNSs4_Rep20_S_empty_rep_storageE

I don't know why it is necessary to have that added to addsym.awk,
when it is already added to the individual mapfiles.

Even if it is necessary, from the issue it seems to me that (at least
at the moment) only the mysql connector is affected, and furthermore
only in debug mode. Mac/PPC uses probably won't use either of those,
so I guess it is fine to just omit it for Mac/PPC and keep it for the
other systems..
