Hello,
when bash is being cross-compiled it can't detect if getenv can be
redefined...
configure:14432: checking to see if getenv can be redefined
configure:14438: WARNING: cannot check getenv redefinition if cross
compiling -- defaulting to yes
configure:14489: result: yes
...so it defaults to 'yes', and can cause build failures like this one:

In function `__GI_getenv':

./lib/sh/libsh.a(getenv.o):getenv.c:(.text+0x0): first defined here

What do you think about adding a new configure option like
"--with-getenv=yes|no" to explicitly state if getenv has to be redefined?
Thanks.
