[EXEC] Fixed _PATH_BSHELL warning
With klcc we get klcc -DHAVE_CONFIG_H -I. -I.. -include ../config.h -DBSD=1 -DSHELL -DIFS_BROKEN -Wall -D__CTYPE_NO_INLINE -MT exec.o -MD -MP -MF .deps/exec.Tpo -c -o exec.o exec.c exec.c: In function 'tryexec': exec.c:160: warning: comparison with string literal results in unspecified behavior Storing it in a local variable fixes the problem. Thanks to Dan McGee for reporting this. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
