Bug report
The configure script is missing a space in the test for--as-needed, falsely detects the platform as supporting that GNU ld specific flag then fails later in the build with the error:
gcc -I/usr/local/include -I/usr/local/ssl/include -D__EXTENSIONS__=1 -D_XPG6=1 -D_REENTRANT -I/usr/local/include/ncurses -DHAVE_NCURSES_H=1 -DHAVE_TERM_H=1 -fno-semantic-interposition -shared -L. -L/usr/local/lib/ -L/usr/local/lib -L/usr/local/ssl/lib -L/usr/local/lib/amd64 -Wl,-R/usr/local/lib -Wl,-R/usr/local/ssl/lib -Wl,-R/usr/local/lib/amd64 -L/usr/lib -L/lib -fno-semantic-interposition -fprofile-generate -Wl,--no-as-needed -o libpython3.so -Wl,-hlibpython3.so libpython3.11.sold: fatal: unrecognized option '--no-as-needed'ld: fatal: use the -z help option for usage informationThe root cause is this misdetection, because configure is doingas_fn_append LDFLAGS -Wl,--no-as-needed instead ofas_fn_append LDFLAGS " -Wl,--no-as-needed" in

Presumably this will also impact other platforms that don't support that flag,
