Subject: offer REALGCC variable to configure musl-gcc wrapper at runtime
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=0b3e2257fa9f4c4773f8aec1bdbccbc46a4d9477;hp=f600105eef74a636a0efd1f1d07170ce5df9aa64;ds=sidebyside

offer REALGCC variable to configure musl-gcc wrapper at runtime

this is useful when the underlying gcc is already a wrapper, which is
the case at least on some uclibc-based system images. it's also useful
for running an older/newer/nondefault version of gcc.
