um: add work around for build problems with bash 4
|
|
|
|
Building User Mode Linux fails with bash 4. The UML Makefiles use an
|
|
environment variable called CPPFLAGS_vmlinux.lds but bash 4 does not
|
|
export environment variables with a dot in their name. Add a hack to
|
|
allow building UML with bash 4 (which should not affect other shells).
