Hi Adrian,

Trying to build/run glibc testsuite against sh4 own toolchain I am facing
an build issue for some tests:

gcc -nostdlib -nostartfiles -o /home/azanella/glibc/glibc-git-build/assert/tst-assert-c++    -Wl,-z,combreloc -Wl,-z,relro -Wl,--hash-style=both /home/azanella/glibc/glibc-git-build/csu/crt1.o /home/azanella/glibc/glibc-git-build/csu/crti.o `gcc  --print-file-name=crtbegin.o` /home/azanella/glibc/glibc-git-build/assert/tst-assert-c++.o /home/azanella/glibc/glibc-git-build/support/libsupport_nonshared.a -lstdc++ -Wl,-dynamic-linker=/lib/ -Wl,-rpath-link=/home/azanella/glibc/glibc-git-build:/home/azanella/glibc/glibc-git-build/math:/home/azanella/glibc/glibc-git-build/elf:/home/azanella/glibc/glibc-git-build/dlfcn:/home/azanella/glibc/glibc-git-build/nss:/home/azanella/glibc/glibc-git-build/nis:/home/azanella/glibc/glibc-git-build/rt:/home/azanella/glibc/glibc-git-build/resolv:/home/azanella/glibc/glibc-git-build/crypt:/home/azanella/glibc/glibc-git-build/mathvec:/home/azanella/glibc/glibc-git-build/support:/home/azanella/glibc/glibc-git-build/nptl /home/azanella/glibc/glibc-git-build/ /home/azanella/glibc/glibc-git-build/libc_nonshared.a -Wl,--as-needed /home/azanella/glibc/glibc-git-build/elf/ -Wl,--no-as-needed -lgcc -Wl,--as-needed -lgcc_s  -Wl,--no-as-needed `gcc  --print-file-name=crtend.o` /home/azanella/glibc/glibc-git-build/csu/crtn.o
/usr/lib/gcc/sh4-linux-gnu/7/ undefined reference to `__fpscr_values@GLIBC_2.2'
collect2: error: ld returned 1 exit status

I did not dig into this, but some google shows it has been an issue before [1].
The issue is using cross toolchain I did not see any
issues building glibc testsuite.

The major gcc configuration differences I see is system one adds a 
'--with-cpu=sh4 --with-multilib-list=m4,m4-nofpu'. Any idea of what might
be happening.
