I'm getting a failure to detect wxGTK3-devel in a cmake project that I am

My host system is fedora-32 x86_64, and I'm trying to build for fedora-rawhide 
x86_64.

It looks like the bash "test(1)" command is not behaving properly, strange as 
that may sound...

Can you try running mock with "--isolation=simple" and check if that
fixes the problem?
If yes, then you're hitting this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1869030
If no, then I have no idea what's going on :)

That's it.  Using --isolation=simple works.

If I run "wx-config --libs" I get:

# wx-config --libs
wxGTK3-devel isn't installed for architecture 'x86_64'

even though I can see that wxGTK3-devel is installed:

# rpm -q wxGTK3-devel
wxGTK3-devel-3.0.5.1-2.fc33.x86_64

wx-config should end up running "/usr/lib64/wx/config/gtk3-unicode-3.0 --libs" 
and if I run that command directly I get:

# /usr/lib64/wx/config/gtk3-unicode-3.0 --libs
-pthread   -lwx_gtk3u_xrc-3.0 -lwx_gtk3u_webview-3.0 -lwx_gtk3u_html-3.0 
-lwx_gtk3u_qa-3.0 -lwx_gtk3u_adv-3.0 -lwx_gtk3u_core-3.0 -lwx_baseu_xml-3.0 
-lwx_baseu_net-3.0 -lwx_baseu-3.0

exactly as I'd expect.

Here is a trace of wx-config running, after I added set -x and set -e to the 
script:

# wx-config --libs
+ set -e
+ version=3.0
+ '[' 1 -ge 2 ']'
+ '[' -z ']'
++ uname -m
+ arch=x86_64
+ case $arch in
+ libdir=/usr/lib64
+ wxconfig=/usr/lib64/wx/config/gtk3-unicode-3.0
+ '[' '!' -f /usr/lib64/wx/config/gtk3-unicode-3.0 ']'
+ '[' '!' -f /usr/lib64/wx/config/gtk3-unicode-3.0 -a '(' x86_64 = ppc64 -o 
x86_64 = sparc64 ')' ']'
+ echo /usr/lib64/wx/config/gtk3-unicode-3.0
/usr/lib64/wx/config/gtk3-unicode-3.0
+ '[' -x /usr/lib64/wx/config/gtk3-unicode-3.0 ']'
+ echo 'wxGTK3-devel isn'\''t installed for architecture '\''x86_64'\'''
wxGTK3-devel isn't installed for architecture 'x86_64'
+ exit 9

Basically,  wx-config finds the correct gtk3-unicode-3.0 script 
(wxconfig=/usr/lib64/wx/config/gtk3-unicode-3.0) but then wx-config refuses to run it 
because '[' -x /usr/lib64/wx/config/gtk3-unicode-3.0 ']' fails to identify 
gtk3-unicode-3.0 as executable.  I already know gtk3-unicode-3.0 is executable, because I 
ran it manually above.  And if I do an "ls", I get:

# ls -l /usr/lib64/wx/config/gtk3-unicode-3.0
-rwxr-xr-x 1 root root 48362 Jul 30 16:03 /usr/lib64/wx/config/gtk3-unicode-3.0

so gtk3-unicode-3.0 is surely executable.

If I manually run "test", it does in fact fail to detect properly:

# [ -x /usr/lib64/wx/config/gtk3-unicode-3.0 ] ; echo $?
1

But "test" does admit that the file exists:

# [ -e /usr/lib64/wx/config/gtk3-unicode-3.0 ] ; echo $?
0

I hesitate to write a bug for this because it is so bizarre that I figure I 
must be doing something wrong, although I have no idea what that might be.

BTW, wx-config works fine under fedora-32 mock, so it appears to be something 
particular to rawhide mock.

Any hints appreciated.
