Fix a problem with the libgo testsuite using a method to determine the
compiler to use resulting in the tool being different from one the
library has been built with, and causing a catastrophic failure from the
lack of a suitable `--sysroot=' option where the `--with-build-sysroot='
configuration option has been used to build the compiler resulting in
the inability to link executables.
Address this problem by providing a DejaGNU configuration file defining
the compiler to use, via the GOC_UNDER_TEST TCL variable, set from $GOC
by autoconf, which will have all the required options set for the target
compiler to build executables in the environment configured, removing
failures like:
.../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory
.../bin/riscv64-linux-gnu-ld: cannot find -lm
.../bin/riscv64-linux-gnu-ld: cannot find -lc
collect2: error: ld returned 1 exit status
compiler exited with status 1
No summary comparison, because the libgo testsuite does not provide one
in this configuration for some reason, however this change improves
overall test results for the `riscv64-linux-gnu' target (here with the
`x86_64-linux-gnu' host and RISC-V QEMU in the Linux user emulation mode
as the target board) from 0 PASSes and 159 FAILs to 133 PASSes and 26
FAILs.

previously set.

As we've found, this is conceptually problematic, as discussed in
<https://inbox.sourceware.org/875y868a4b.fsf@euler.schwinge.homeip.net>
"Consider '--with-build-sysroot=[...]' for target libraries' build-tree testing (instead of build-time 'CC' etc.)
[PR109951]".
I therefore suggest to apply to libgo the conceptually same changes
as I've just pushed for libgomp:
<https://inbox.sourceware.org/874jjzzqc2.fsf@euler.schwinge.homeip.net>
"libgomp: Consider '--with-build-sysroot=[...]' for target libraries' build-tree testing (instead of build-time 'CC'
etc.) [PR91884, PR109951]".
OK to push (via Ian/Go upstream) the attached
"libgo: Consider '--with-build-sysroot=[...]' for target libraries' build-tree testing (instead of build-time 'CC' etc.) [PR109951]"?
By the way, I've tested this one via hard-coding
'libgo/configure.ac:USE_DEJAGNU' to 'yes', and observing that my
"quick hack to replicate the original requirement"
('internal_error ("MISSING SYSROOT");') no longer triggers.
Grüße
Thomas
