Recently we have add the capability to adding extra compilation options
for running GCC testsuite, but it seems not handle well on the `make report`
part, it will ignore extra compilation options, and then...combine
multiple report together.

Now it will put in two different line, and the extra compilation options
will listed in follwoing line, here is example output here:

               ========= Summary of gcc testsuite =========
                            | # of unexpected case / # of unique unexpected case
                            |          gcc |          g++ |     gfortran |

Extend semantic for option '--with-extra-multilib-test'

Signed-off-by: Pan Li <pan2.li@intel.com>

The `--with-extra-multilib-test` take the format like below for now.

"<arch>-<abi>-[code-model][;<arch>-<abi>-[code-model]*"

This patch would like to extend the sematic to support additional buil
options for each combination. Aka:

"<arch>-<abi>-[code-model][:opts]*[;<arch>-<abi>-[code-model][:opts]*]*"

opts can be one or more build options splited by ':'. For example as
below:

* --param=riscv-autovec-lmul=m1
* --param=riscv-autovec-lmul=dynamic:--param=riscv-autovec-preference=fixed-vlmax

Thus the full example of the option `--with-extra-multilib-test` will be:

`rv64gcv_zvl128b-lp64d:--param=riscv-autovec-lmul=m1;rv64gcv_zvl256b-lp64d:-
-param=riscv-autovec-lmul=dynamic:--param=riscv-autovec-preference=fixed-vlmax`

Specify vector spec v1.0 in QEMU arguments.

Remove unused frameworks to give CI more disk space

Some testcases in GCC's testsuite check stdout.
Qemu will print a warning if the vector spec is not specified which will cause those testcases to fail.

The warning:
vector version is not specified, use the default value v1.0

NOTE: This is toolchain developer facing feature.

This allow user to add extra testing multi-lib arch, it's useful when
develop and/or testing new extensions.

Usage:

--with-extra-multilib-test="arch-abi[;arch-abi]"

e.g.

linux enable enabled multilib, so default will build with follwoing
configuration:

lib32/ilp32;@march=rv32imac@mabi=ilp32
lib32/ilp32d;@march=rv32imafdc@mabi=ilp32d
lib64/lp64;@march=rv64imac@mabi=lp64
lib64/lp64d;@march=rv64imafdc@mabi=lp64d

But you want to testing more on vector stuffs like rv32gcv and rv64gcv,
then you can configure with `--with-extra-multilib-test="rv32gcv-ilp32d;rv64gcv;lp64d"`

Then the testing will run rv32imac-ilp32 rv32imafdc-ilp32d
rv64imac-lp64 rv64imafdc-lp64d and rv32gcv-ilp32d;rv64gcv;lp64d!

NOTE: Extra multilib test settings still require existing
multilib has support those extra settings, e.g. you can't add
rv32imafc_zbb-ilp32f on above example since no compatible multilib has
provided.
