The linker's <code>-s</code> and <code>-w</code> flags are now behave more
consistently across all platforms.
The <code>-w</code> flag suppresses DWARF debug information generation.
The <code>-s</code> flag suppresses symbol table generation.
The <code>-s</code> flag also implies the <code>-w</code> flag, which can be
negated with <code>-w=0</code>.
That is, <code>-s</code> <code>-w=0</code> will generate a binary with DWARF
debug information generation but without the symbol table.

On ELF platforms, the <code>-B</code> linker flag now accepts a special form:
with <code>-B</code> <code>gobuildid</code>, the linker will generate a GNU
build ID (the ELF <code>NT_GNU_BUILD_ID</code> note) derived from the Go
build ID.
