Log Message:
fix the libstdc++ build for GCC 14.

some parts of the libstdc++ build have different flags for different
files *only* for the shared library version of the build.  netbsd
share/mk has no current method of doing this, so introduce support
for having "CSHLIBFLAGS.$file" like we do for other options, and use
it to add -D_GLIBCXX_SHARED to *most* but not all files.

this is a copy of from gcc not dot old:
