bash fails to link for static builds with uClibc toolchains due to
getenv redefinitions. This is caused because bash is unable to check if
getenv is already defined when cross-compiling, so it defaults to 'yes':

configure:14438: WARNING: cannot check getenv redefinition if cross
compiling -- defaulting to yes

We can avoid this redefinition by passing bash_cv_getenv_redef=no to the
configure script.
