./configure fails to link test program due to missing dependencies

Hej and hello!

I am tinkering with LFS 12.1 and I ran into a problem to compile git 2.44.0 with https/curl support due to an error in the ./configure script for the libcurl detection.

The relevant section of config.log:

configure:5462: checking for curl_global_init in -lcurl configure:5485: gcc -o conftest -g -O2   conftest.c -lcurl   >&5 /usr/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/13.2.0/../../../../lib/libcurl.a(libcurl_la-content_encoding.o): in function `zstd_do_close': content_encoding.c:(.text+0x78): undefined reference to `ZSTD_freeDStream' /usr/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/13.2.0/../../../../lib/libcurl.a(libcurl_la-content_encoding.o): in function `zstd_do_write': content_encoding.c:(.text+0x112): undefined reference to `ZSTD_decompressStream' /usr/bin/ld: content_encoding.c:(.text+0x11a): undefined reference to `ZSTD_isError' ...

If I set LDFLAGS to whatever pkg-config --libs libcurl says on my system (actually: -lcurl -lssl -lcrypto -lzstd -lbrotlidec -lz) then it compiles just fine. If I add LDFLAGS to the configure environment it will accept that test, and then detect, as expected, the pkg-config settings for libcurl.

Should not ./configure FIRST check for a pkg-config environment without assuming that even the most trivial curl programs should compile without any additional dependencies like zstd etc?

Thank you for your help and have a great weekend!
