Commit 2cfa86a54882(package/erlang: bump version to 26.0.2) added a
patch to restore building on uClibc.
However, that patch is not upstream, and has been rejected:
https://github.com/erlang/otp/pull/7500
Please open a PR to https://github.com/asmjit/asmjit instead and we
will get the fix next time we sync with upstream. We do not want
theirs and our implementation to diverge.
Furthermore, it happens to work on uClibc, because uClibc does not
expose sys/auxv.h, but it fails to work on glibc, because the define is
not propagated to "sub-trees", and thus is never defined where it is
checked for, even when sys/auxv.h is available. This causes build
failures such as:
asmjit/core/cpuinfo.cpp: In function ‘void asmjit::_abi_1_10::detectHWCaps(CpuInfo&, long unsigned int, const LinuxHWCapMapping*, size_t)’:
asmjit/core/cpuinfo.cpp:840:24: error: ‘getauxval’ was not declared in this scope
840 | unsigned long mask = getauxval(type);
| ^~~~~~~~~
asmjit/core/cpuinfo.cpp: In function ‘void asmjit::_abi_1_10::detectARMCpu(CpuInfo&)’:
asmjit/core/cpuinfo.cpp:972:21: error: ‘AT_HWCAP’ was not declared in this scope
972 | detectHWCaps(cpu, AT_HWCAP, hwCapMapping, ASMJIT_ARRAY_SIZE(hwCapMapping));
| ^~~~~~~~
asmjit/core/cpuinfo.cpp:973:21: error: ‘AT_HWCAP2’ was not declared in this scope
973 | detectHWCaps(cpu, AT_HWCAP2, hwCapMapping2, ASMJIT_ARRAY_SIZE(hwCapMapping2));
| ^~~~~~~~~
Yet, sys/auxv.h was detected at configure time:
checking for sys/auxv.h... yes
This defconfig is enough to reproduce the error:
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_PACKAGE_ERLANG=y
Since upstream refused the patch, and there is no fix that was submitted
to the actual upstream (asmjit), drop the rejectred patch, and disable
for uClibc: the patch is incorrect, and we can't fix a build issue on
uClibc by introducing another on glibc.

Erlang is a programming language used to build massively
|
|
scalable soft real-time systems with requirements on high
|
|
availability. Some of its uses are in telecoms, banking,
|
|
e-commerce, computer telephony and instant messaging.
|
|
Erlang's runtime system has built-in support for
|
|
concurrency, distribution and fault tolerance.

The Megaco application is a framework for building

applications on top of the Megaco/H.248 protocol. It is

approximately 14MB in size so if you do not need it then

it is recommended not to enable it.
