gbuild: work around GDB 10 bug with DWARF5 in split debug info mimo-7-0-branch-pointlibreoffice-7-0
GCC 11 defaults to -gdwarf-5 and GDB can only read it if -gsplit-dwarf isn't used. Dwarf Error: wrong unit_type in compilation unit header (is DW_UT_split_compile (0x05), should be DW_UT_type (0x02)) [in module /workdir/CObject/desktop/source/app/main.dwo] https://sourceware.org/bugzilla/show_bug.cgi?id=27354 https://bugzilla.redhat.com/show_bug.cgi?id=1956475 Change-Id: Ie2ac7193a29a8f257cf6f1d711f9fa6941df48ad Reviewed-on: https://gerrit.libreoffice.org/c/core/+/115054 Tested-by: Jenkins Reviewed-by: Michael Stahl <michael.stahl@allotropia.de> (cherry picked from commit dc8c8a4aa20ddd3139a25d5c052cac9bae944cb8) Reviewed-on: https://gerrit.libreoffice.org/c/core/+/115193 Reviewed-by: Caolán McNamara <caolanm@redhat.com>
