Bug #10821: mkmf.rb: Incorrect have_devel? test depending on run order
https://bugs.ruby-lang.org/issues/10821

* Author: Joshua Peek
* Status: Open
* Priority: Normal
* Assignee:
* ruby -v: ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin14.0]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
have_devel? is usually lazily checked on the first call to try_do(). However, try_do() may be invoked within the scope of a with_ldflags or with_cflags block. If have_devel? is checked for the first time with altered test LDFLAGS or CFLAGS it may crash.

~~~
# extconf.rb
$LDFLAGS = "-L/custom/path/to/lib
try_ldflags "-Issl"
# try_ldflags -> try_link -> try_do -> have_devel (with incorrect $LDFLAG in scope)
~~~
