libasn1c is using libm[ath] symbols from REAL.c and hence should be
linked using '-lm' to carry a dynamic linker dependency itself.
We shouldn't use a pkg-config hack to ask applications to do this on
our behalf.

The libosmocore depedency is used for talloc and OSMO_ASSERT.
Reduce the depedencies by using libtalloc directly and replace
the ASSERT with a local one (without backtrace support).
... which in turn causes all the ASN_DEBUG() to be turned into
fprintf(stderr, ...) statements, once the user application decides
to set 'asn_debug = 1' somewhere in its code.
The next step would be to make _ASN_DECODE_FAILED / _ASN_ENCODE_FAILED
no longer depend on ASN_DEBUG (which it currently does)
