daemon: Fix linking gcrypt when --as-needed linker arg is used
This is a followup to 8a7bd211d21f06c1234fbb82bb905d202d58f598.
As it is mentioned in autoconf manual that library names should be
specified in LIBS, not LDFLAGS. See:
https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.72/html_node/Preset-Output-Variables.html#index-LDFLAGS-2
This change also brings back the save_* vars trick that was there
before. I missed in my earlier change that nix/local.mk was referring
LIBGCRYPT_* vars directly.
And, instead of CXXFLAGS, CPPFLAGS is used since the latter is probably
more correct as this is used for include dirs, therefore using
preprocessor flags.
Tested with ./configure LDFLAGS="-Wl,--as-needed" --with-libgcrypt-prefix=... combinations.
* config-daemon.ac: Set ‘LIBGCRYPT_CPPFLAGS’ instead of
‘LIBGCRYPT_CXXFLAGS’. Set ‘LIBGCRYPT_LIBS’ in addition to
‘LIBGCRYPT_LDFLAGS’. Save and restore ‘CPPFLAGS’, ‘LDFLAGS’, and ‘LIBS’
around test.
* nix/local.mk (libutil_a_CPPFLAGS): Add $(LIBGCRYPT_CPPFLAGS).
(libstore_a_CXXFLAGS): Remove $(LIBGCRYPT_CFLAGS).
(guix_daemon_LDFLAGS): New variable.
