Hi Rene & List,
Cross building for Mips64,
During the 2nd pass of glibc (after building gcc)
I got the following failure:
make[2]: ***

Seems like it needs the -fgnu89-inline option to compile.
was not able to get it to work by stoking config.cache, but it did work
when I added it directly to the gcc options:
