Subject: [PATCH] or1k: Only define TARGET_HAVE_TLS when HAVE_AS_TLS
This was found when testing buildroot with linuxthreads enabled. In
this case, the build passes --disable-tls to the toolchain during
configuration. After building the OpenRISC toolchain it was still
generating TLS code sequences and causing linker failures such as:
..../or1k-buildroot-linux-uclibc-gcc -o gpsd-3.24/gpsctl .... -lusb-1.0 -lm -lrt -lnsl
..../ld: ..../sysroot/usr/lib/libusb-1.0.so: undefined reference to `__tls_get_addr'
This patch fixes this by disabling tls for the OpenRISC target when requested
via --disable-tls.
gcc/ChangeLog:
* config/or1k/or1k.cc (TARGET_HAVE_TLS): Only define if
HAVE_AS_TLS is defined.
