the configure.ac script stack protector test to actually work.

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.
