RFR 8241053: Hotspot runtime/CommandLine/OptionsValidation/TestOptionsWithRanges.java test fails on Alpine Linux with debug build

[Alexander Scherbatiy]

Hello,

Could you review the fix for the issue:
   Bug: https://bugs.openjdk.java.net/browse/JDK-8241053
   Webrev: http://cr.openjdk.java.net/~alexsch/8241053/weberv.00

The following tests fail on Linux Alpine with musl libc:
   test/hotspot/jtreg/runtime/Thread/TestThreadStackSizes.java
test/hotspot/jtreg/runtime/CommandLine/OptionsValidation/TestOptionsWithRanges.java

This is because muls pthread_attr_setstacksize(3) function 
implementation [1] returns EINVAL when stack size exceeds the certain limit.

According to POSIX pthread_attr_setstacksize() function description [2]:
  The pthread_attr_setstacksize() function will fail if:
     [EINVAL]  The value of stacksize is less than PTHREAD_STACK_MIN or 
exceeds a system-imposed limit.

The proposed fix excludes EINVAL value from assert_status() and for the 
EINVAL return value makes the same cleanup actions and returns false 
from os::create_thread() function as it is done for AIX[3].

To reproduce the issue it needs to build Portola from repository [4] 
using instructions from JEP 386: Alpine Linux/x64 Port [5].
After the fix both TestThreadStackSizes.java and 
TestOptionsWithRanges.java tests pass on Alpine Linux with musl libc and 
on Ubuntu 18.0.4.
