Summary: SDCC deletes linker output when name does not match first .o

Initial Comment:
When linking z80 .o files, SDCC produces no output if the output file name given with -o does not match the name of the first module (with suffixes removed.)

For example, this will work:

sdcc -mz80 -o a.ihx a.o b.o

While this will fail, for the same .o files:

sdcc -mz80 -o output.ihx a.o b.o

Using strace it can be seen that the linker correctly produces the ihx file, but sdcc subsequently deletes it because it expects the linker to produce a file named after the first module, and assumes the output of link-z80 is an old file. So this is what strace sees in the first working example:

rename("a.ihx", "a.ihx")          = 0

And in the none working example this happens:

unlink("output.ihx")                      = 0
rename("a.ihx", "output.ihx")          = -1 ENOENT (No such file or directory)
