Description: Fix empty awk function
gcc/config/i386/i386-builtin-types.awk defines and calls a function named
"attribute_mode" with zero statements.
.
BusyBox awk prints the following error message when building GCC:
.
awk: …/gcc/config/i386/i386-builtin-types.awk:164: Call to undefined function
.
This seems to be due to lines 2664 and 2665 of editors/awk.c in BusyBox 1.21.0,
which throw a syntax error if the called function has no nodes in its node
chain:
.
if (!op->r.f->body.first)
syntax_error(EMSG_UNDEF_FUNC);
