Well, with `-pie' one can issue 'foo.so' by itself:
$ ./foo.so
foo.so: version 0.1
This feature is quite useful in practice -- for example, the
GNU C library is runnable this way too:
$ /lib64/libc.so.6
GNU C Library stable release version 2.11.3 (20110527), by Roland McGrath et
al.
...
On the other hand, I deem the above use-case to be not that
useful whilest developing a library -- when one may use e.g.
`--coverage'.
Therefore, I myself have no problem with my (real) Makefile
discriminating 'LDFLAGS' as below:
ifeq (${COVERAGE},yes)
CFLAGS += --coverage
LDFLAGS += --coverage -shared
else
LDFLAGS += -pie
endif
