This bot features GCC8.4. Interestingly the Debian Stable bot, which features GCC8.3, is building OK (https://build.webkit.org/#/builders/46/builds/15837)

I attempted to build bmalloc and libpas with -fPIC enabled as the log error indicates but it didn't fix the error.

[Mike Gorse]

I am also seeing this on openSUSE Leap 15.4, but it builds successfully on openSUSE Tumbleweed.

[Diego Pino]

There's a way of working around this error by building using 'USE_SYSTEM_MALLLOC=ON' For example:

```
$ Tools/Script/build-webkit --gtk --release --cmakeargs=-DUSE_SYSTEM_MALLOC=ON
```
