gcc-runtime: fix LSB library checks for libstdc++.so.6
[YOCTO #795]
When we run library check of LSB on qemux86 and qemuppc, we got some failures
about 'libstdc++.so.6'.
Test environment:
Platform: Qemu-x86, Qemu-ppc
lsb image: poky-image-lsb-qemux86-test.ext3(Feb 26th, auto-build server)
Library check of LSB: 4.1.0-1
The error log:
Did not find _ZNKSt5ctypeIcE8do_widenEPKcS2_Pc (GLIBCXX_3.4) in libstdc++.so.6
Unmangled symbol name: std::ctype<char>::do_widen(char const*, char const*,
char*) const
...
found that some weak symbols ('W') change into local ('t') during link time
and be stripped. According to compiling log, the option
"-fvisibility-inlines-hidden" is used for gcc. And this option caused some weak
symbols change into local.
see http://bugzilla.pokylinux.org/show_bug.cgi?id=795 for more information on the bug.
