scripts/functions: fix endless loop in debug-shell with IO redirection

CT_DEBUG_INTERACTIVE is disabled when stdin, stdout or
stderr are redirected, but the check is only done at
the start of the build and doesn't catch when individual
build commands use redirection. When stdin is redirected
it will cause the debug shell to exit immediately, causing
and endless loop. Thus, save the stdin/our/err file handles
and restore them before invoking the debug shell.

     1 This patch is needed on newer uclibc becuase the uclibc header generation
     2 mechanism generates the sysnum.h properly NR_cacheflush is defined for ARM
     3 but there is no cachectl.h file which is exported to userspace. Strace 
     4 assumes that if SYS_cacheflush is defined than it icludes asm/cachectl.h
     5 which breaks the build for ARM now.
     6 
     7 This patch adds a check for ARM architecture.
