Subject: libgcc errors
Previously i emailed about an issue i was having with no response. I
rebuilt the cross toolchain with the latest versions and switched from 3.X
to 2.6 kernel headers to try to work around the issue but still get the
same error compiling libgcc of which now it points to a config.log. I
pulled that log and here is the part leading up to the error, if you want
the rest or anything else please let me know.
Im trying to find out why after using the musl patch and specifying
--target or --host=i686-linux-musl I recieve this issue compiling libgcc,
This only happens if i specify the host or target as musl.
I appreciate any help you can provide.
It was created by GNU C Runtime Library configure 1.0, which was
generated by GNU Autoconf 2.64. Invocation command line was
