...and also use configure options instead of environment variables. 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 adding bash_cv_getenv_redef=no to the configure options. At the same time, we use configure options instead of environment variables because there is no need to pass those options to the configure script as environment variables. Doing it in this way we avoid the risk of environment variables leaking into places we don't expect.
