No Fedora 20, eu preciso instalar um driver Linux para uma determinada placa de porta serial PCI Express que é fornecida pelo fabricante. Para fazer isso, eu tenho que compilar o código-fonte do driver. Quando eu emito o comando "make" no diretório do código fonte, recebo o seguinte erro:
[root@localhost driver]# make
make[1]: Entering directory '/usr/src/kernels/3.16.6-203.fc20.i686+PAE'
Makefile:649: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler
make[1]: *** No rule to make target 'Tech'. Stop.
make[1]: Leaving directory '/usr/src/kernels/3.16.6-203.fc20.i686+PAE'
make: *** [modules] Error 2
O arquivo "Makefile" é o seguinte:

A versão do kernel do Linux é:
[root@localhost driver]# uname -r
3.16.6-203.fc20.i686+PAE
E a versão do compilador do gcc é:
[root@localhost driver]# gcc -v
Using built-in specs.

Como corrijo isso para poder compilar este driver?
