[PATCH] devtools/test-meson-builds: reduce output size

[Bruce Richardson]

The various builds done by the "test-meson-builds.sh" script can take a
large amount of space on disk. Some simple changes allow us to reduce
the space used significantly. Specifically:
* use the default "release" build, which does not include debug
  information, for builds where we won't check ABI.
* use shared linkage rather than static for the 32-bit builds.

After making these changes a set of builds produced by test-meson-builds
shrank from ~17G to ~7G on my system.
