spec option fails if gcc is installed in a path with
spaces

Proposed patch
The "%{!shared:%:if-exists(default-manifest.o%s)}" spec option fails if gcc is
installed in a path with spaces.
It turns out the problem lies in gcc.c where the spec "%s" function will expand
"default-manifest.o" into "D:/msys
64/mingw64/x86_64-w64-mingw32/lib/default-manifest.o" or so which is correct,
but because of the if-exists function, it will be tested and further expanded
into "D:/msys" and "64/mingw64/x86_64-w64-mingw32/lib/default-manifest.o"
(split at the space) which is then passed to collect2 and fails.
