[Tinycc-devel] [PATCH 7/7] tcc -E: Let output_default be <file>.o instead of a.out

[Kirill Smelkov]

This affectes where `tcc -E -MD file.c` will place generated dependency
information -- previously, for `tcc -E` output_default was a.out, and so
deps were put into a.d .

Avoid this behaviour, by treating `tcc -E` as `tcc -c` with respect to
output_default computation.

This will not hurt anything else (preprocessor outputs to either stdout,
or to explicitely given (-o <file>) destination, so no default filename
is used here), and on the other hand `tcc -E -MD file.c` now puts
dependencies into file.d (the same behaviour as for gcc -E).
