Subject: [PATCH] make-binaries: Fix building Termcap and Linux-PAM

Building GNU Termcap and Linux-PAM using the updated toolchain both
failed, since crosstool-NG now uses GCC 14.x, which turns the
"implicit-function-declaration" warning into an error.  See:

https://gcc.gnu.org/gcc-14/porting_to.html#warnings-as-errors

Therefore, specify "CFLAGS=-Wno-error=implicit-function-declaration" to
turn this error back into a warning.
