Julien Olivain bf952b0cb7 support/config-fragments: fix bootlin-x86-i686-musl
Commit a8be4a04ad "support/config-fragments: replace
br-i386-pentium-mmx-musl" replaced this old toolchain by
bootlin-x86-i686-musl.

When using test-pkg with all toolchains, bootlin-x86-i686-musl is always
failing. The issue can be reproduced with for example:

    utils/test-pkg -a -p busybox

The issue can also be reproduced with a simple config like:

    cat > .config <<EOF
    BR2_i386=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
    BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_X86_I686_MUSL_STABLE=y
    BR2_PACKAGE_BUSYBOX=y
    EOF
    make olddefconfig
    make

Compilation fail with output:

    Cannot execute cross-compiler '/i586-linux-gcc'

This issue happen is because the toolchain can never be selected.

The config fragment [1] selects BR2_i386 alone.

The target architecture variant default to i586 if target
architecture is i386. See [2].

Finally, the generated toolchain options includes a depends on
BR2_i386 and !BR2_x86_i586, making the toolchain always ignored.
See [3].

This commit fixes the issue by adding BR2_x86_i686=y to the
bootlin-x86-i686-musl.config fragment as suggested by the
Bootlin toolchain fragment [4].
