各位大神，我做交叉编译器的时候遇到这个问题了，crosstool-ng-1.9.3,不知道怎么办了

[INFO ] Extracting and patching toolchain components
[ERROR] The 'linux-2.6.33.7' sources were partially extracted.
[ERROR] Please remove first:
[ERROR] - the source dir for 'linux-2.6.33.7', in '/opt/crosstool-ng-1.9.3/crosstool-ng-1.9.3_build/.build/src'
[ERROR] - the file '/opt/crosstool-ng-1.9.3/crosstool-ng-1.9.3_build/.build/src/.linux-2.6.33.7.extracting'
[ERROR] I'll stop now to avoid any carnage...
