[Buildroot] [PATCH 2/2] package/erlang-jiffy: fix build failure due to lack of -fPIC

[Giulio Benetti]

Package erlang-jiffy needs to be linked with -fPIC otherwise it throws
linker error:
```
failed with return code 1 and the following output:
/home/giuliobenetti/br_reproduce/60296a48210e7ffc6bc9fa50ee586441a8957e85/output/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-buildroot-linux-musl/9.3.0/../../../../x86_64-buildroot-linux-musl/bin/ld: /tmp/jiffy.so.FCaOXC.ltrans1.ltrans.o: relocation R_X86_64_PC32 against symbol `dec_destroy' can not be used when making a shared object;
recompile with -fPIC
```

This is architecture indipendent, so let's add -fPIC flag to LDFLAGS in any
case.

Fixes:
