Thomas Herz 20560e8dca Ninja: Do not use newlines in response files with Windows GNU tools (#15439)
Since commit v2.8.11~213^2 (Ninja: Avoid LNK1170 linker error, 2013-02-01)
we generate linker response files with "$in_newline" to support a large
number of object files with the MS link.exe tool.  However, the GNU linker
on Windows does not understand the newline endings that Ninja puts in the
response files.  Switch back to "$in" for that case.
