GNUrl, GNUnet and alpine-linux

[xrs]

Hi,

since the last changes on gnunet concerning gnurl/curl detection I have
a strange behaviour in the context of packaging gnunet for
alpine-linux. 

When building gnunet-0.19.3 with gnurl-7.72.0[2] the
process stops at detecting libcurl. (See also [1].) 
...
checking for conversation feature set to build... none
checking for curl_easy_getinfo in -lcurl-gnutls... no
checking for gawk... (cached) awk
checking for curl-config... no
checking whether libcurl is usable... no
...

This used to work. 

Now, when building gnunet-0.19.3 with curl-7.87.0 I get no error in the
configure phase which is strange, because I expected that gnunet would
only compile with gnurl or curl-gnutls.
...
checking for conversation feature set to build... none
checking for curl_easy_getinfo in -lcurl-gnutls... no
checking for gawk... (cached) awk
checking for curl-config... /usr/bin/curl-config
checking for the version of libcurl... 7.87.0
checking for libcurl >= version 7.34.0... yes
checking whether libcurl is usable... yes
checking for curl_free... yes
checking for curl/curl.h... yes
checking whether CURLINFO_TLS_SSL_PTR is declared... yes
checking for library containing __atomic_load_8... -latomic
...

Right now it would be possible to package gnunet with libcurl
(OpenSSL) on alpine-linux.

Do I misunderstand something here?

Cheers,
xrs
