build,cares,openssl,zlib: limit symbol exports #27664
Description
On Windows, Node exports a curated list of symbols from its dependencies that don't use dllimport/dllexport (c-ares, openssl, zlib)
On Unices, Node indiscriminately re-exports everything thanks to -Wl,--whole-archive.
There's a comment about it in node.gyp:
# TODO(bnoordhuis) Make all platforms export the same list of symbols.
# Teach mkssldef.py to generate linker maps that UNIX linkers understand.It would be good to implement that. It should help trim down the binary size.
