When trying to build headers, it tries to detect if binutils supports --hash-style option, while trying to ld using gcc.

make -j2 headers
make: mips-unknown_softfloat-linux-uclibc-gcc: Command not found
Rules.mak:665: *** Your binutils do not support --hash-style option, while you want to use it.  Stop.
emake failed

Once progressed I get:

More fixes.
1. Do not try to execute gcc while building headers.
2. Do not enable LDSO_GNU_HASH_SUPPORT in mips as "ld: .gnu.hash is incompatible with the MIPS ABI"
3. Set UCLIBC_HAS_FPU to n if tc-is-softfloat.

Comment 6 Oleg 2018-01-08 12:04:51 UTC

I got same error mipsel-hardfloat-linux-uclibc and latest patch fixed it.

uclibc support in Gentoo has been removed.
