Subject: checksyscalls: fix "here document" handling
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0e75898fe2499ece0ac3f1475982a828b3283b0d;p=openwrt%2Fstaging%2Fblogic.git

checksyscalls: fix "here document" handling

"echo" doesn't read from stdin, therefore the checksyscalls script didn't
warn about not implemented system calls anymore since 29dc54c6
("checksyscalls: Use arch/x86/syscalls/syscall_32.tbl as source").

Use "cat" instead of "echo" which handles this correctly.
