LO 7.0 alpha1 on bigendian (here: s390x)

[Rene Engelhard <rene@xxxxxxxxxx>]

Hi,

tried to build LibreOffice 7.0 alpha1 on !x86_64. So far it failed only
on s390x (big endian!):

1.)

#if defined OSL_LITENDIAN
            aResult = OUString(reinterpret_cast<const sal_Unicode *>(
                m_pData.get() + nStartOff), nCount);
#else
            OUStringBuffer aBuf;
[...]

in source/filter/ww8/WW8Sttbf.cxx. On bigendian it fails since it cannot
resolve OUStringBuffer (but suggests rtl::'ing it).

See https://gerrit.libreoffice.org/c/core/+/93865

Erm, seriously? LO is supporting s390x in the code.

Lubos, what are you suggesting on s390x? --disable-skia? Isn't it needed for "gen" also on Linux?
