+Subject: [PATCH] configure.ac: use CC instead of gcc, full link for stack
|
|
|
+ protector test
|
|
|
+
|
|
|
+Using gcc directly is incorrect when cross-compiling, $CC should be
|
|
|
+used instead.
|
|
|
+
|
|
|
+Also, for the stack protector test, a full link is needed, since just
|
|
|
+the compilation can work, but the link can fail due to libssp not
|
|
|
+being available in the toolchain.
