While compiling OpenADK I discovered that
there may be a case where UCLIBC_EXTRA_LDFLAGS
contains `-fpie -pie`. Linker ignores `-shared`
if `-pie` flag is passed after and produces
an executable binary instead of shared object.
This leads to linking failure because `ld-uClibc.so.1`
becomes executable instead of shared object.
`ld-uClibc.so.1` is used as one of the inputs
when linking of libc.so.1 and linking proccess fails.
To prevent this issue we need to pass extra `-shared` flag
in `link.so` target command after all other flags to overwrite
`-pie` effect.
