aux and dump revamp: fix target exec suffix handling
HAVE_TARGET_EXECUTABLE_SUFFIX is defined only in gcc.c, and in a way
that requires testing whether it's defined, rather than for nonzero.
Fixed the new use in gcc.c, copied the fix and the definition to
lto-wrapper.c.
for gcc/ChangeLog
* lto-wrapper.c (HAVE_TARGET_EXECUTABLE_SUFFIX): Define if...
(TARGET_EXECUTABLE_SUFFIX): ... is defined; define this to the
empty string otherwise.
(run_gcc): Test for HAVE_TARGET_EXECUTABLE_SUFFIX with defined.
* gcc.c (process_command): Likewise.
