tier2 not clean

[Vladimir Kempik]

it’s an interesting bug/feature.

I was building riscv jdk with cross-compilation.
first step was to build build-jdk for host system (x86_64) from the same source code ( bootjdk = jdk18_x86_64)
second step was to build risc-v jdk using build-jdk from previous step and bootjdk = jdk18_x86_64

the issue were cause by disabling C2 (jvm options : -compiler2) in build-jdk ( and only in build-jdk)
this resulted in FDBigInteger class being missed in lib/classlist file ( it’s a symptom tho)
while the class were still present in java.base.mod

for some reason it was affecting not only build-jdk but the final jdk too.

After removing -compiler2 from --with-jvm-features of build-jdk the test passes

Regards, Vladimir
