Subject: [PATCH] configure: Pass LDFLAGS to link tests
|
|
|
|
LDFLAGS can contain critical flags without which linking wont succeed
|
|
therefore ensure that all configure tests involving link time checks are
|
|
using LDFLAGS on compiler commandline along with CFLAGS to ensure the
|
|
tests perform correctly. Without this some tests may fail resulting in
|
|
wrong confgure result, ending in miscompiling the package
|
