openwrt编译evas时总是出错，据说可能是m4的问题才导致：
./configure: line 23122: syntax error near unexpected token `edb,'
./configure: line 23122: ` EVAS_CHECK_LOADER_DEP_EDB(edb, have_evas_image_loader_[]DOWN="yes", have_evas_image_loader_[]DOWN="no")'
详细的：
checking whether to enable Software Windows CE 16 bits rendering backend... no
checking whether Software Windows CE 16 bits rendering backend will be built... no
checking whether to use SDL primitive when possible... no
checking whether to enable Edb image loader... no

有没有人试过？
或者对m4比较熟悉（我是一窍不通）
