-shell/ash.c: fix ice on mips while compiling with -g -O
-
-Build busybox on mips with -g -O, there is a ice failure:
-...
-shell/ash.c:8758:1: internal compiler error: in dwarf2out_var_location, at dwarf2out.c:21264
-...
-Please submit a full bug report,
-with preprocessed source if appropriate.
-See <http://gcc.gnu.org/bugs.html> for instructions.
-{standard input}: Assembler messages:
-{standard input}: Warning: missing .end at end of assembly
-{standard input}: Error: open CFI at the end of file; missing .cfi_endproc directive
-...
-
-The following line caused the ice failure on mips:
-...
-void evaltreenr(union node *, int) __attribute__ ((alias("evaltree"),__noreturn__));
-...
-So remove evaltreenr which was a alias of evaltree, and use evaltree
-to instead.
