sys-devel/gdb: link against tinfow first, then tinfo. bug #669096
In bug #669096 gdb was directly linked both to libtinfo.so.6 and libncursesw.so.6: $ lddtree /usr/bin/gdb /usr/bin/gdb (interpreter => /lib64/ld-linux-x86-64.so.2) libtinfo.so.6 => /lib64/libtinfo.so.6 libncursesw.so.6 => /lib64/libncursesw.so.6 libtinfow.so.6 => /lib64/libtinfow.so.6 ... and caused gdb to SIGSEGV at start. Let's consistently link against *w libraries when both available. Note: the fix on it's own is not enough: - we don't pass include paths to ncursesw libraries - libreadline.so.7 is still linked against libtinfo.so.6 in Gentoo and needs a separate fix. But it's enough to make immediate SIGSEGV to go away.

+Try to link gdb against tinfow first, then tinfo.
+
+In bug #669096 gdb was directly linked both
+to libtinfo.so.6 and libncursesw.so.6:
+ $ lddtree /usr/bin/gdb
+ /usr/bin/gdb (interpreter => /lib64/ld-linux-x86-64.so.2)
+ libtinfo.so.6 => /lib64/libtinfo.so.6
+ libncursesw.so.6 => /lib64/libncursesw.so.6
+ libtinfow.so.6 => /lib64/libtinfow.so.6
+ ...
+and caused gdb to SIGSEGV at start.
+
+Let's consistently link against *w libraries.
+
+Note: the fix on it's own is not enough:
+- we don't pass include paths to ncursesw libraries
+- libreadline.so.7 is still linked against libtinfo.so.6 in Gentoo
+ and needs a separate fix.
+
+But it's enough to make immediate SIGSEGV to go away.
