Subject: meson: make nm binary optional
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ff9bf223c24143260a975f45963eb90f40565c57;p=mesa.git

meson: make nm binary optional

This makes nm not required, but used if found. In general I imagine that
this means that on windows nm wont be found, and on other platforms it
will.

v2: - fix gbm and egl symbols check tests to only be run if nm is found
    - reword commit message to reflect the code change
